I'm trying to install a simple node webserver following the example in Pro AngularJS from apress.
I've installed node.js and the connect and karma modules.
I do get a warning when I installed karma via: "npm install -g karma" that says "optional dep failed, continuing" but then seems to install correctly.
I created a server.js based on the example:
var connect = require('connect');
connect.createServer(
connect.static("../angularjs")
).listen(5000);
when I run it I get TypeError:Undefined is not a function pointing to connect.static.
Apparently in the latest build of connect the static middleware has been moved to it's own package.
nodejs connect cannot find static

Laravel Mix Version: 6.0.43
Node Version (node -v): 16.13.1
NPM Version (npm -v): 8.1.2
OS: Windows 10 21h2
Description:
THIS IS HAPPENING ON A FRESH NEW INSTALL OF LARAVEL AND MY OTHER PROJECTS
Running npm run hot changes the script tag sources to http://localhost:8080/*/*.* from http://localhost/*/*.* HOWEVER I always get net::ERR_EMPTY_RESPONSE from localhost:8080. The HMR server doesn't launch at all. The terminal output of the command also have no mention of spinning up a new web server.
PS C:\Users\Eric Wang\Documents\GitHub\test-laravel-mix> npm run hot

Here's a picture of the browser failing to fetch the bundle files
Steps To Reproduce:
I am running Docker 4.5.1 using legacy Hyper-V.
I containerized Laravel and PHP BUT not the frontend and JS. I am running Laravel Mix on my main system.
Clone the fresh installation of Laravel from https://github.com/ericwang401/test-laravel-mix
Clone Laradock in the project folder using git clone https://github.com/laradock/laradock.git
CD to the Laradock folder and make .env file with cp .env.example .env
Inside .env file set PHP_VERSION to PHP_VERSION=8.0 AND DO NOT EDIT MYSQL SETTINGS
Now edit the Laravel environment file
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=default
DB_USERNAME=default
DB_PASSWORD=secret
Start up the Laravel app in Laradock folder using docker-compose up -d nginx mysql
Enter into bash mode in the Docker container docker-compose exec workspace bash
Install Composer dependencies BUT NOT NPM DEPENDENCIES YET composer i
Now exit out of the Docker container CNTRL + D
Install NPM dependencies in project root ON YOUR MAIN SYSTEM npm i
Run on your main system npm run hot
Now go to http://localhost and IT SHOULD be a white screen
Check console logs and it should give net::ERR_EMPTY_RESPONSE when it tries to fetch the bundle files
REMEMBER: the backend is running inside Docker
The frontend (Laravel Mix) is running on the host system
This issue is happening on a FRESH project installation of Laravel 9 + Jetstream AND it's also happening on my other older projects like https://github.com/StratumPanel/Stratum-Panel
The HMR server is simply not launching.
I found out the issue. The problem was that the default port, 8080, Laravel Mix HMR was using couldn't be binded to. Webpack Dev Server doesn't respond with a message of failing to bind to a port. To confirm this issue, I replicated the environment on my friend's PC and it too couldn't bind to port 8080, but this time it reported an error that the dev server couldn't bind to port 8080.
I fixed this issue by specifying
mix.options({
hmrOptions: {
host: 'localhost',
port: 4206
}
});
And it works! On both my friend's pc and my pc.
I used the exact same reproduction instructions on my friend's PC.
I spent way too long investigating this issue 😭
I have never setup things this way, I got it running locally but have no clue how I should have do it when I deploy it into an ec2 server
I have a node app running already in ec2 server but recently I have added spaCy into one of my api.
The basic logic is calling the api which runs node and part of the js script uses spawn to process the proc.py file and do some calculation with outputs.
I have tried the following below to setup on my server but of course it failed when calling the api
my original node app is in /var/www/myApp
I used sudo apt install virtualenv then inside my /var/www/myApp I ran the command virtualenv venv which creates the virtual environment...
I did a source venv/bin/activate to get into the virtual environment
Then I started running the commands to install spacy mentioned in the spacy documentation https://github.com/explosion/spaCy
used this command to install pip install -U spacy and python -m spacy download en
Then I ran python -m spacy validate to see if spacy is installed which I got
Installed models (spaCy v2.0.11)
/var/www/myApp/venv/local/lib/python2.7/site-packages/spacy
TYPE NAME MODEL VERSION
package en-core-web-sm en_core_web_sm 2.0.0 ✔
link en en_core_web_sm 2.0.0 ✔
which I believe this means the installation is a success.
But after this, I am not sure what I should do to continue.
I tried running my api but getting this as an error message "err": "Traceback (most recent call last):\n"
I would believe the spacy module is not being called that's why I am getting this error but I am not sure what I should do to get this working.
Would really appreciate for any help, thanks in advance for any advices.
EDIT:
my proc.py code is below
if __name__ == '__main__':
import sys
import json
import spacy
nlp = spacy.load('en')
text = sys.argv[1]
doc = nlp(text)
all_noun_tokens = [ token.lemma_ for token in doc
if (token.pos_ == 'PROPN'
or token.pos_ == 'NOUN'
or token.tag_ == 'NN'
or token.tag_ == 'NNP') ]
print(json.dumps(all_noun_tokens))
P.S. I am wondering if there's any config that I need to do in order for my app to find where the virtuanenv is so it can detect the spacy module?
So I am trying to deploy a simple meteor app to Google App Engine. I've tried following this tutorial https://cloud.google.com/community/tutorials/run-meteor-on-google-app-engine
But it resulted in
error: Can't find npm module 'meteor-deque'. Did you forget to call 'Npm.depends' in package.js within the 'meteor' package?
Googling resulted in a few more tutorials but via their comments it seems they are outdate as well.
There is also this one https://medium.com/google-cloud/meteor-google-a-devops-post-b8a17f889f84
However this is about deploying to the compute engine, so this is a plan B.
So I wander if any of you successfully deployed Meteor to GAE recently in 2017 with Meteor 1.4? Can you please share details?
Thanks to kiyohiko from meteor forums.

I am trying to setup a node.js app inside docker, using as host the google compute engine VM gci-stable-55-8872-71-0 (debian), from image project google-containers:
$ gcloud compute instances create myvm --image-project google-containers --image gci-stable-55-8872-71-0 --zone europe-west1-b --machine-type f1-micro --scopes compute-rw
then I try to get a docker container running:
$ sudo docker build -t forperfuse/test .
but I keep getting errors when installing node:
The command '/bin/sh -c npm install' returned a non-zero code: 1
all other dependencies install well but node and npm are not installing- I have tried several options but still cannot get it to work, can you please help? many thanks in advance...
I'm not sure about what is going on, looks like the run command in the dockerfile is aiming to a bash that has a weird header. If you can publish them we can try or...
You can use the bitnami docker image available in launcher for free and works like a charm.
https://console.cloud.google.com/launcher
And there search for the node.js image.
I will need any help i can get to install socket.io over node.js for server.
I have already installed the node from the site. I am interested in step- by step(directory,e.t.c) as i am new to programming.
Thanks in advance
James
The easy way to install socket.io is with npm (Node Package Manager). npm is the default package manager for Node.js.The current Windows installer from nodejs.org will install npm along with Node.js. In Windows OS, open the cmd window and type:
npm install socket.io
This command will install socket.io in the local node_modules folder, which is owned by the current user.
npm can also take optional flags which are described at the npm-install webpage of www.npmjs.org.
In order to test if socket.io is working, try this tutorial: Get Started: Chat application which has been linked to by Beterraba in a comment below your question.
