Fresh Ubuntu 16.04 installation. Installed nodejs 10.15 according to the official instructions
# curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
# apt-get install nodejs
Then installed ws globally
# npm install -g ws
+ ws#6.1.3
updated 1 package in 0.374s
Then in a js file I do:
const WebSocket = require('ws');
Then run it:
# nodejs ws.js
internal/modules/cjs/loader.js:583
throw err;
^
Error: Cannot find module 'ws'

It appears the global modules are installed in /usr/lib/node_modules but apps still fail unless I manually say
export NODE_PATH=/usr/lib/node_modules
Is this a bug?

What is it that I am missing here?
Ubuntu's packages seem to be outdated.
Installing using apt-get node-express-generator gives this error.
Installing using npm i -g express-generator works fine.
Please try to follow the preceding steps.
Install the current version of NodeJS
Uninstall all modules with npm uninstall and rm -fr ~/.npm
Reinstall express-generator
Hope it helps.
Not really good with this JavaScript world. Trying to install npm and I think it's broken. I'm using Debian and ran:
apt install npm.
Everything went fine but when I run npm it throws up this error

Nothing works, i can't install the node-uuid either.
I fixed this, I think there's a problem with the package on Debian repo.
I followed the instruction on Node website
https://nodejs.org/en/download/package-manager/
I have npm installed now :)

Try removing your node modules and installing it again:
rm -rf ./node_modules
npm cache clean
npm install

Does anyone have an idea on how to resolve this issue?
There's a bug where underscore.string is set as a devDependency. I've made a PR for it.
In the mean time you can install it manually.
cd /usr/local/lib/node_modules/generator-webapp/ && npm install underscore.string
On Windows, I had to use the following command to resolve this:
npm install -g underscore.string
in any command prompt window.
While trying to install express js by the command "npm install -g express" in cmd prompt in windows it shows the following error
module.js:340
throw err;

How to fix this and run a web server?
You shouldn't install express globally. cd into your project directory, then npm install express.
Global package install is meant to install command line utilities; project dependencies should be installed locally, see npm's FAQ and this blog post.
