[node.js] webpack command not working

I am new to Node Js and Webpack. I tried to start a project with module-loaders.

Firstly, I installed nodeJs and NPM and created a new directory called tutorial. I used the command prompt to cd into this directory and then ran the following command npm init and then installed webpack via npm using the command below :

npm install -S webpack

The 1st command installed webpack locally into the project under the 'node-modules' directory and I can run my project by doing this:

nodejs node-modules/webpack/bin/webpack.js

The problem with this is that I have to place my webpack.config.js file inside of this directory which I want to place in my project root.

One solution to this problem was to install webpack globally on my machine which I did using the command below :

npm install -g webpack

This installed Webpack and now I do have a Webpack command. However, this command does not seem to be working or doing anything at all. When I try to run this from my project's root directroy it does not do anything at all (See Screenshot)

Please tell me what I am doing wrong!!

I had to reinstall webpack to get it working with my local version of webpack, e.g:

$ npm uninstall webpack
$ npm i -D webpack

Actually, I have got this error a while ago. There are two ways to make this to work, as per my knowledge.

1. Server wont update the changes made in the index.js because of some webpack bugs. So, restart your server.
2. Updating your node.js will be helpful to avoid such problems.

You can run npx webpack. The npx command, which ships with Node 8.2/npm 5.2.0 or higher, runs the webpack binary (./node_modules/.bin/webpack) of the webpack package. Source of info: https://webpack.js.org/guides/getting-started/

Installing webpack with -g option installs webpack in a folder in

C:\Users\<.profileusername.>\AppData\Roaming\npm\node_modules

same with webpack-cli and webpack-dev-server

Outside the global node_modules a link is created for webpack to be run from commandline

C:\Users\<.profileusername.>\AppData\Roaming\npm

to make this work locally, I did the following

1. renamed the webpack folder in global node_modules to _old
2. installed webpack locally within project
3. edited the command link webpack.cmd and pointed the webpack.js to look into my local node_modules folder within my application

Problem with this approach is you'd have to maintain links for each project you have. Theres no other way since you are using the command line editor to run webpack command when installing with a -g option.

So if you had proj1, proj2 and proj3 all with their local node_modules and local webpack installed( not using -g when installing), then you'd have to create non-generic link names instead of just webpack.

example here would be to create webpack_proj1.cmd, webpack_proj2.cmd and webpack_proj3.cmd and in each cmd follow point 2 and 3 above

PS: dont forget to update your package.json with these changes or else you'll get errors as it won't find webpack command

npm i webpack -g

installs webpack globally on your system, that makes it available in terminal window.

The quickest way, just to get this working is to use the web pack from another location, this will stop you having to install it globally or if npm run webpack fails.

When you install webpack with npm it goes inside the "node_modules\.bin" folder of your project.

in command prompt (as administrator)

1. go to the location of the project where your webpack.config.js is located.
2. in command prompt write the following

"C:\Users\..\ProjectName\node_modules\.bin\webpack" --config webpack.config.vendor.js
