Error: Cannot find module 'webpack-cli/bin/config-yargs'

Question

\'Github\' asked me to update \'webpack-dev-server\' to version 3.1.11 or higher for security reasons.

However, \'npm run dev\' will not run after the update.

Answer 1

It is because of version of webpack-cli. In some versions, there is no config-yargs.js file. So ^3.3.11 version of webpack-cli worked for me. Try it:

npm i webpack-cli@^3.3.11

Answer 2

To fix it just do 2 things.

1. Install npm i webpack-cli @webpack-cli/init
2. Add this to your package.json:

   "scripts": {
     "start": "webpack-cli serve --mode development"
   },
   

Done!
