webpack-dev-server Cannot find module 'webpack'

Question

I\'m trying to use webpack-dev-server to run a simple program but I\'m getting this error:

module.js:471
    throw err;
    ^

Error: Cannot find module \'we         


        

Answer 1

I had the same problem, but I resolved by installing additional webpack-cli

npm install --save-dev webpack-cli

Answer 2

npm install --save-dev webpack is not enough.

You also have to install the following:

npm install --save-dev webpack-dev-server 

And optionally, you can also install:

npm install --save-dev webpack-dev-middleware webpack-hot-middleware
