A total node noob here. I've been trying to set up a sample node app but the following error keeps popping up every time I try to run:
node app
Failed to load c++ bson extension, using pure JS version

I guess you did not have the make tools available when you installed your mongodb library. I suggest you do
xcode-select --install (on a mac)
or sudo apt-get install gcc make build-essential (on ubuntu)
and run
rm -rf node_modules
npm cache clean
npm install
OR just npm update based on #tobias comment (after installing build-essential)
npm update
I just resolved that.
When you install the mongoose module by npm, it does not have a built bson module in it's folder. In the file node_modules/mongoose/node_modules/mongodb/node_modules/bson/ext/index.js, change the line
bson = require('../build/Release/bson');
to
bson = require('bson');
and then install the bson module using npm.
I have sorted the issue of getting the "Failed to load c++ bson extension" on raspbian(debian for raspberry) by:
npm install -g node-gyp
and then
npm update
I was unable to solve this
until now. First of all you have to have system packages mentioned by Pradeep Mahdevu. Those are:
xcode-select --install (on a mac)
or
sudo apt-get install gcc make build-essential (on ubuntu)
Then I've installed node-gyp
npm install -g node-gyp
like datadracer said but npm update also suggested by him is risky. It update all modules, which can be dangerous (sometimes API changes between versions).
I suggest going into node_modules/mongodb/node_modules/bson directory and from there use
node-gyp rebuild
That solved the problem for me.
A common problem is that node-gyp requires Python 2.x and if your system's python points to 3.x, it will fail to compile bson, without warning. You can fix this by setting a python global key in your npm config that points to the 2.x executable on your system. For example, on Arch Linux:
npm config -g set python "/usr/bin/python2"
On WIN 8.1
It seems I used a wrong version of mongoose in my package.json file.
I removed the line "mongoose" : "^3.8.15" from package.json.
CLI:
npm install mongoose --save
Now it says "mongoose": "^4.0.6" in package.json and the error I had is gone.
I'm running Ubuntu 14.04 and to fix it for me I had to create a symlink for node to point to nodejs as described here:
nodejs vs node on ubuntu 12.04
Once I did that I re-ran these commands:
rm -rf node_modules
npm cache clean
npm install
So in my case, I first tried to check under this directory /node_modules/mongoose/node_modules/, just to confirm that I have the bson module.
I figured out that I did not have it in the first place, then I just run
npm install bson
and then
npm update
All got sorted.Tried and tested in Ubuntu.
just wanted to say I also had the error
Failed to load c++ bson extension, using pure JS version
But with none of the other errors. I tried everything and turns out the mongodb drivers that I was specifying in the package.json file was incompatible with my version of MongoDB. I changed it to my latest version which was (1.4.34) and it worked!!!
sudo npm rebuild was what fixed it for me.
I finally corrected this error by updating my mongodb dependency version to ~2.0.36 in package.json.
"dependencies": {
"consolidate": "~0.9.1",
"express": "3.x",
"mongodb": "~2.0.36",
"mongoose": "^4.1.12"
}
Unfortunately, All the above answers are only half right..
Took a long time to figure this out..
Mongoose bson install via npm throws warning and causes the error...
npm install -g node-gyp
git clone https://github.com/mongodb/js-bson.git
cd js-bson
npm install
node-gyp rebuild
This works like magic!!
For me it only take to run these commands in my api directory:
rm -rf node_modules
npm cache clean
npm install
I just ran:
sudo npm install bson
and
sudo npm update
and all become ok.
The bson extension message is just a warning, I get it all the time in my nodejs application.
Things to check:
MongoDB instance: Do you have a MongoDB instance running?
Config: Did you correctly configure Mongoose to your MongoDB instance? I suspect your config is wrong, because the error message spits out a very weird string for your mongodb server host name..
I fixed this problem on CentOS by
sudo yum groupinstall "Development Tools"
sudo npm install -g node-gyp
rm -r node_modules
npm cache clean
npm install
I fixed it by changing line 10 of:
/node_modules/mongoose/node_modules/mongodb/node_modules/bson/ext/index.js
from:
bson = require('../build/Release/bson');
to:
bson = require('bson');
I also got this problem and it caused my sessions not to work. But not to break either...
I used a mongoose connection.
I had this:
var mongoose = require('mongoose');
var express = require('express');
var cookieParser = require('cookie-parser');
var expressSession = require('express-session');
var MongoStore = require('connect-mongo')(expressSession);
...
var app = express();
app.set('port', process.env.PORT || 8080);
app.use(bodyParser);
mongoose.connect('mongodb://localhost/TEST');
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function callback () {
console.log('MongoDB connected');
});
app.use(cookieParser());
app.use(expressSession({
secret: 'mysecret',
cookie: {
maxAge: null,
expires: moment().utc().add('days',10).toDate(),// 10 dagen
},
store: new MongoStore({
db: 'TEST',
collection: 'sessions',
}),
Very straightforward. But req.session stayed always empty.
rm -rf node_modules
npm cache clean
npm install
Did the trick. Watch out you dont have a 'mongodb' in your package.json! Just Mongoose and connect-mongo.
Here's how I fixed the problem on Ubuntu:
ln -s /usr/bin/nodejs /usr/bin/node
npm install node-gyp
cd node_modules/mongodb/node_modules/bson
node-gyp rebuild
Inspired by #mbochynski answer, but I had to create a symbolic link first, otherwise the rebuild failed.
i was having same trouble tried so many options but in the last npm intall in my mean app folder worked.
I had this problem because I was including the node_modules folder in my Git repository. When I rebuilt the node_modules on the other system it worked. One of them was running Linux, the other OS X. Maybe they had different processor architectures as well.
I had the same problem on my EC2 instance. I think the initial cause was because I had a Node instance running when I installed Mongo. I stopped the Node service and then ran
sudo npm update
inside of the top level folder of my node project. This fixed the problem and everything was just like new
I was trying to run node on virtual machine (vagrant) shared folder. That was a problem. My host machine is Windows, installed node on Windows and worked like a charm. So if you are using virtual machine, just try to run node server on host machine.
I just had the same problem and literally nothing worked for me. The error was showing kerberos is causing the problem and it was one of the mongoose dependencies. Since I'm on Ubuntu, I thought there might be permission issues somewhere between the globally installed packages -- in /usr/lib/node_modules via sudo, and those which are on the user space.
I installed mongoose globally -- with sudo of course, and everything began working as expected.
P.S. The kerberos package now also is installed globally next to mongoose, however I can't remember if I did it deliberately -- while I was trying to solve the problem, or if it was there from the beginning.
I'm working on Docker with centOS 7, and encountered the same problem.
after looking around, and make several tries, I fixed this problem by installing mongodb, and mongodb-server
yum install mongodb mongodb-server
I don't think this is the best way to produce the minimal container. but I can limit the scope into the following packages

For Windows 7.1, these directions helped me to fix my build environment:
https://github.com/mongodb/js-bson/issues/58#issuecomment-68217275
http://christiankvalheim.com/post/diagnose_installation_problems/
I was able to resolve by uninstalling and reinstalling monk package.
Initial install seemingly had a corrupt mongodb/bson dependency.
Followint #user1548357 I decided to change the module file itself. So as to avoid the problems pointed out by the valid comments below I included my changes in a postinstall script so that I can set it and forget it and be assured that it will run when my modules are installed.
// package.json
"scripts": {
// other scripts
"postinstall": "node ./bson.fix.js"
},
and the script is:
// bson.fix.js
var fs = require('fs');
var file = './node_modules/bson/ext/index.js'
fs.readFile(file, 'utf8', function (err,data) {
if (err) {
return console.log(err);
}
var result = data.replace(/\.\.\/build\/Release\/bson/g, 'bson');
fs.writeFile(file, result, 'utf8', function (err) {
if (err) return console.log(err);
console.log('Fixed bson module so as to use JS version');
});
});
easily kick out the problem by just add this line both try and catch block
path: node_modules/mongoose/node_modules/mongodb/node_modules/bson/ext/index.js
bson = require('bson'); instead
bson = require('./win32/ia32/bson');
bson = require('../build/Release/bson');
That is all!!!
The only thing which helps me on Windows 7 (x64): https://stackoverflow.com/a/29714359/2670121
Reinstall node and python with x32 versions.
I spent a lot of time with this error:
Failed to load c++ bson extension
and finally, when I installed module node-gyp (for building native addons) and even installed windows SDK with visual studio - nodejs didn't recognize assembled module bson.node as a module. After reinstalling the problem is gone.
Again, What does this error mean?
Actually, it's even not error. You still can use mongoose. But in this case, instead of fast native realization of bson module, you got js-realization, which is slower.
I saw many tips like: "edit path deep inside node_modules..." - which is totally useless, because it does not solve the problem, but just turned off the error messages.

I’m collaborating with the programmers involved in the ferdi project.
https://getferdi.com/
Ferdi motto is :"All your messaging services in one place ". Infact it is like franz and it works on a lot of oses,such as mac os M1,windows,ubuntu x64 bit. And we are trying to make it work also on the arm64 / jetson nano / Tegra. Unfortunately on this os it does not work correctly because we have a javascript error that we aren’t able to fix. This is how to reproduce it :
[ `root#zi-desktop` ](mailto:root#zi-desktop) `:~/Desktop/zi/Work/I9/Virt/dockers/arm64/ferdi2# ferdi`

(running as normal user gives the same error)
Basically we use a docker container like this to produce the deb packages that we will install on the os . Below u can see the Dockerfile for arm64 / tegra / jetson nano :
`FROM node:fermium-buster`
`LABEL Author="ZioMario <` [ `marietto2008#gmail.com` ](mailto:marietto2008#gmail.com) `>"`

`WORKDIR /ferdi`
`RUN git clone` [ `https://github.com/getferdi/ferdi.git` ](https://github.com/getferdi/ferdi.git) `. && git submodule update --init --recursive`
`RUN npx lerna bootstrap`
`RUN cd recipes && npm i && npm run package`
`RUN npm run build`
It is working everywhere,except on the jetson nano. do u have some ideas about how to fix it ? thanks.
In these cases usually try to delete the package-lock.json and node_modules, then try to run npm install again.
Also looks like you have a problem related to the "main" prop in package.json. The main property of a package.json is a direction to the entry point to the module that the package.json is describing.
For example in a Node.js application, when the module is called via a required statement, the module's exports from the file named in the main property will be what's returned to the Node.js application.
I'm using Windows (64-bit) with Node.js and npm installed.
In my project file, I have run the following commands:
npm init
npm install discord.js --save
npm install ffmpeg --save
Now i just created the code for a basic bot here is the main code.
I list here the important:
if (message.content === '!play' && message.member.roles.has(message.guild.roles.find("name", config.role_name).id)) {
if (!message.member.voiceChannel) return log("?");
message.member.voiceChannel.join().then(function (connection){
});
}
Then, in Discord, I say the following:
[1517932146] Musik bot loaded
(node:35760) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: FFMPEG not found
I have already tested the following:
reinstallation of everything
others of the require names e.t.z.
simplify the code
So if you have any ideas then let me know.
Solution
npm i ffmpeg-binaries#3.2.2-3
link
You need to actually install ffmpeg, the ffmpeg module on NPM simply exports a wrapper API for ffmpeg's command-line interface.
You can download ffmpeg's binaries from the website or use a package manager (like apt on Ubuntu, brew on Mac or choco on Windows) which usually takes care of dropping the binaries into a directory that is present in the PATH.
To install on windows using choco. Please ensure you running cmd/windows powershell/ windows terminal as administrator or it will fail here ...
choco install ffmpeg
To install on linux
sudo apt install ffmpeg
As far as I can see, you never actually installed ffmpeg. Using the ffmpeg node module won't get you anywhere unless you install the binaries.
You can also use apt, brew or in your case choco which makes things go alot faster. Here is a guide on how to do it in windows.
Once it is installed you will be able to use many node modules such as opusscript and much more.
I'm using windows 8.1 x64 with all updates.
I was using nodejs 8.9.1 - I took an error on command "npm -v".
So I uninstalled this version and install 8.9.3. It gave me same error on the command.
And then I uninstalled 8.9.3 and clean all paths using this answer;
https://stackoverflow.com/a/20711410/1143249
Then installed new version 9.3.0...
But still, I'm getting same error in all npm commands.
What am I missing? How can I solve this problem?

Thanks for all answers ( until this date: 10.02.2018 03:30 PM GTM+3 )
( I've completed some of my jobs with vm windows until this date but now I've sad news.)
I ran out all options and I have still a lot work to do with npm packages.
So, I've formatted my machine and replace with Windows 10 Enterprise x64.
I can't try new answers now but here is golden point what I've learned;
If you have mission critical machine like ci-build (jenkins etc.) or
if you don't have more than one computer (And vm is not an option)
Just backup your drive completely at time to time because you will never know
your computer softwares (like node - npm) could give an interesting errors such as this. That's what I learned, just saying...
The workaround is to ensure that C:\Users\{user}\AppData\Roaming\npm exists and is writable with your normal user account.

Although haven't tested Node on Windows 8, I suggest you get rid of npm installation under AppData folder altogether. You can achieve this by using a Node version manager. I recommend Nodist. You can easily switch between versions as well.
With Nodist you can run the command as such:
nodist 6.2.10
One of the things I suspect is Node runtime's limited access to required files under C:/ drive - maybe something related to Windows 8. That said, you could install nodist in any drive other than C:/. Meanwhile as mentioned by #fjoe, stick with LTS versions especially v6.x.x.
Here are a few things to consider when picking your node.js version.
Version labelled as LTS (Long Term Support) are the releases they stand behind.
You can see a full list of versions here notice the LTS column. It is also interesting to see the versions of V8 and npm that are packaged with each.
Node 9.* has no official LTS release.
Node 8.* officially entered LTS on 10-31-2017 (3 months ago).
I personally have run into problems with it.
Node 7.* never officially released as LTS.
Node 6.* has 2 years of official LTS releases and they are continuing to support it.
With the most recent release on 01-02-2018.
Given this information might I recommend you try the proven long supported version 6.*
If this works then maybe hold off on version 8.* until more things get ironed out.
Other people have commented on your question about environment variables for node or npm. This is obviously not the issue as the commands are recognized and running (but they error).
Also I would recommend you follow this full uninstall guide: How to completely remove node.js from Windows
My coding buddy had a similar error yesterday, although on Linux.
The error was in the node_modules folder, so removing that and reinstalling node solved it for him.
That would be your node_module folder in AppData\Roaming\npm.
I guess the problem can be in NPM itself.
try to update your NPM.
Try to use this great approach
By the way, it's great to know what npm version you have with your changes of node.js versions.
From the logs you provided it looks like a cache bug, because of some junk that previously exists and that is causing issues.
Open the command prompt with admin privileges and follow the below steps:
1) Clear the cache: npm cache clean --force. You can also run npm cache verify.
2) Delete node_modules folder using: rm -rf node_modules.
3) Delete any package-lock.json file.
4) Remove the .npm directory.
5) Remove following directories :
5.1) C:\Users\<username>\AppData\Roaming\npm\.
5.2) C:\Users\<username>\AppData\Roaming\npm-cache.
6) Also, Try by setting environment variables:
C:\Users\<username>\AppData\Roaming\npm;C:\Program Files\nodejs.
Type in the command line: which npm.
Maybe you did not set the system value : NODE_PATH it should point to your global module location.
7) Update to the latest npm with npm i -g npm#latest.
Hope the above trick resolve your issue.
Thanks.
I guess while installing Node.js it don't able to set it's environment path due to permission.
You Need to configure Node path manually into environment variables.
I am working through the tutorial on the jspm.io site
https://github.com/jspm/jspm-cli/wiki/Getting-Started
All works fine until I get to item 3, where I try to execute
jspm install jquery
and I get this error message
warn Error on getOverride for jspm:github, retrying (2).
ReferenceError: ui is not defined
at c:\Projects\Project1\node_modules\jspm\node_modules\jspm-registry\registry.js:157:5
nodejs is v0.12.0
npm is 2.5.1
jspm is 0.14.0
and this is on Windows 8.1
Does anyone have any clue what is causing this?
This looks like it was because there was an error while jspm was trying to create the local registry clone. Ensure you have git installed as git on your machine. Otherwise it may be a permissions issue.
This was a logging bug though - have fixed it with an update to the registry, so that the error should be slightly more useful next time if you update jspm.
I was getting a similar error with jspm but my problem was actually in how nodejs child_process.exec was calling the git command.
child_process.exec was running
C:\Windows\system32\cmd.exe /s /c "git clone --depth=1 github.com/jspm/registry.git .
However cmd.exe was still auto running commands set in the registry first. In my case the command changing the working folder. So the cwd was being overridden.
Check your registry settings for:
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun
If there is a command in there to set the drive of working folder it will cause the above error.
Also
With your working folder as c:\, try ruuning the following nodejs code:
var exec = require('child_process').exec;
exec('dir', { cwd: 'C:/windows/fonts' }, function(error, stdout, stderr) {
console.log('stdout: ' + stdout);
});
If it does not list the contents of the fonts folder then your problem is more likely with child_process.exec in node
I have a few related questions about node-gd and Meteor.

meteorite node-gd
I am passing coordinates back to the server and I want to use node-gd to manipulate an image on the server.
This is my Meteor method:
Meteor.methods({
createImage: function(coords) {
console.log('createImage')
console.log(coords.x);
var gd = require('gd');
}
});
When I try to run this function I get this on my terminal:
I20140826-06:44:18.166(-7)? Exception while invoking method 'createImage' ReferenceError: require is not defined

The answer to this question suggests various JS solutions. Is this what I need, can anyone recommend what's best to use for Meteor for both server and client?
You can't add NPM modules to meteor this way, you should use the npm atmosphere package from meteorhacks : http://atmospherejs.com/package/npm
What you need to do is install the package via meteorite :
mrt add npm
Then add a packages.json in your project root and specify the node-gd dependency :
{
"node-gd":"0.2.3"
}
Finally, in your server code use Meteor.require to access the node-gd API.
Be aware though that Meteor server side programming uses Fibers so you'll have to wrap async API calls to node-gd using either Meteor._wrapAsync or the set of Async utilities that come with the npm atmosphere package.
Here is a nice article on understanding this point : https://www.discovermeteor.com/blog/understanding-sync-async-javascript-node/
You can't use NPM packages on the client.
Try using Meteor.npmRequire('your module name')
