I am trying to create a local server for visual studio code through Node by following Microsoft's Blog Post. I followed these very simple instructions exactly by adding a package.json file in my root folder and running npm install first. When I do, I get the following error:
$ npm install
npm ERR! Windows_NT 10.0.14393
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install"

And yes, I have node installed.
You are using the wrong type of quotes ( windows type ) use this character : "
It looks like you edited the package.json with an editor that automatically uses "smart quotes" (like Microsoft Word, for example). Try retyping the “ characters in Notepad, for example, and see if it works then.
The error message in you package.json
You must use double quotes.
Check and validate your package.json file in here
It looks like when you copy pasted
"name": "Demo”,
it got changed to
“name”: “Demo”,
The problem is with the quotes. Replace all instances of “ or ” with ", and you should be good.

I am trying to setup a express.js server using there generator. I have followed the documation and I have succesfully created the basic structure. However if I try to run the given command (SET DEBUG=transcriptverificationserver:* & npm start) to start the server I always get the following error:
npm ERR! Missing script: "start"
npm ERR!
npm ERR! Did you mean one of these?

I assume its an issue within the package.json file. The script part looks as following:
"scripts": {
"start": "node ./bin/www"
},
I haven´t change anything in the files or structure and I was simply copying the commands from the documentation (https://expressjs.com/en/starter/generator.html)
Thanks for any help in advance
I have tried it again and this time everthing works. I am not sure what has happend before but I might have used the old installation method.
$ npm install -g express-generator
$ express
With my secound try I ensured to use the new method:
$ npx express-generator
I'm trying to start a new project using gruntjs.
I have this project structure:
grunt-test (dir)
|_ index.html
|_ package.json
|_ Gruntfile.js
|_ assets (dir)
|_ _js (dir)
|_ scripts.js
|_ _sass (dir)
|_ style.sass
I have nodejs and grunt installed.
So, when I go to project's folder and use this command line on terminal: npm install grunt --save-dev
It returns me all those errors:
npm ERR! Failed to parse json
npm ERR! Unexpected end of input
npm ERR! File: /Applications/XAMPP/xamppfiles/htdocs/grunt-test/package.json
npm ERR! Failed to parse package.json data.

I've been trying to install it for a while and I haven't had any success. I don't know what I'm doing wrong. I'm following all the instructions on gruntjs docs. Can someone help me?
Your package.json is not a valid JSON. Instead of typing in commands, you can add these as devDependencies in your package.json file and then use npm install which will install packages from the package.json file. You can use the below.
{
"name": "Project Name",
"version": "1.0.0",
"devDependencies": {
"grunt": "0.4.4",
"grunt-cli": "0.1.13"
}
}
Run npm install grunt-cli -g if grunt is not found message gets displayed.
In your package.json, strings are enclosed into single quotes ('), it makes it a non-valid JSON data. JSON expects strings to be enclosed into double quotes (").
I'm sort of new to this whole "node" js thing. When trying to install the MEAN package from http://mean.io/, I followed these steps faithfully:
I "cd" to my directory, run "npm install", and then the "grunt" command, and get this error:
Error: Cannot find module 'coffee-script'
So I roll with the punches. npm install coffee-script, run "grunt" again.
Error: Cannot find module 'getobject'
Ever patient, I decide "okay, forget grunt". I run "node server". Then I get this error:
Error: Cannot find module 'merge-descriptors'
What's wrong? How can I get MEAN working here? (I thought npm was supposed to make life easier).
Update 12/31/13: When I look at the output of npm install, there are a number of "Error: EMFILE" errors. As I understand those errors are related to too many files being opened and graceful-fs is a solution to this. Sample EMFILE error pasted below:
npm ERR! System Darwin 13.0.0
npm ERR! command "node" "/usr/local/bin/npm" "install"
npm ERR! cwd /Users/cnokes/Desktop/mean-master
npm ERR! node -v v0.10.7
npm ERR! npm -v 1.2.21
npm ERR! path /Users/cnokes/Desktop/mean-master/node_modules/grunt/node_modules/iconv-lite/README.md
npm ERR! code EMFILE

With graceful-fs installed, I re-run npm install and get a couple of these errors:
npm ERR! Error: ENOENT, utime '/Users/cnokes/Downloads/mean-master2/node_modules/express/node_modules/fresh/index.js'
I've run in to this and think this might be connected to another issue.
Basically it's related to the number of open files (alot) that get open when we do a npm install.
It has been blogged about nicely here - http://otaqui.com/blog/1618/how-to-fix-error-emfile-too-many-open-files-from-yeoman-and-npm/
and I update the mean FAQ

ok ... first time I'm trying my hand at node.js.
installed it a while back, and not sure how i installed it.
last night, decided to tackle a tutorial regarding node.js and express.
checked my version of node which is v0.8.14 and npm which is 1.1.65. (I'm on Mac, 10.6.8 version)
but did this anyway
npm install -g express
seemed to go ok ... but whenever I tried to generate a new application via
express new ProjectName
I got this:
-bash: express: command not found
Decided to try
sudo npm install express -g
which again seemed to go well ... but again, the express new ProjectName got the same statement.
tried again:
npm install -g express
got a lot of errors unlike the first time.

and so it went on and on: errors ... or no errors. I'm at total loss. and online literature on fixing this problem seems rather sparse.
advice, please?
oh, also saw this somewhere online: (whatever it means)
/usr/local/share/npm/bin/express
which resulted in this:
destination is not empty, continue?
destination is not empty, continue? (yes or no) yes

Sounds like you need to edit your path variable.
Edit your ~/.bash_profile. Add this export somewhere.
export PATH=/usr/local/bin:$PATH:/usr/local/share/npm/bin
What's happening is that node isn't setting up its PATH correctly. I've had this happen to me before. Its something they should fix.
You may not have a .bash_profile. In *nix systems, there are a few different files you can place in your home directory to add environment variables and such.
bash_profile is the one I prefer, so in the terminal cd to ~ and touch .bash_profile.
Then edit it via nano .bash_profile or whatever editor you like.
(In nano, control-o to save, control-x to exit.)
When you've added it, do: source .bash_profile
Then try which express and see if it shows the path.
I am using Windows 7 64bit, trying to install bson as a dependencie of mongodb.

What is the problem?
Also: I tried to install versions 0.1.1, 0.1.2, 0.1.3 etc.
I was having the same exact issue and remembered I had fiddled with my PATH variable, recently. It was failing to run cmd.exe.
It was fixed after adding c:\windows\system32 to my PATH.
Per below (note the node issue mentions socket.io, which was also causing similar problems when I tested it):
https://github.com/joyent/node/issues/4222
Try deleting C:\Users\Administrator\Drop
box\Projekte\Wochenplaner\node_modules and reinstalling.
I just installed the bson package on my Win7 (64bit also) box without any issues.
Check the following points.
Is your node executable accessible from everywhere? (check with opening a command line and just type node + Enter, if a shell pops up you should be fine)
Do you have sufficent access rights for the target folder in question?
Since the main error seems to be CreateProcessW: Das System kann die angegebene Datei nicht finden., i'm pretty sure the first point is the issue.
You could fix that easily by either re-installing node.js or adding the path to your node executable manually to the PATH environment variable.
