When running npm run dev, I got the following error message:

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

Exit status 1 npm ERR! npm ERR! Failed at the coursetro-eth@1.0.0 dev script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

My enviroment is the following:

OS: Windows 10
NPM: Version 5.6.0
WebPack: Version 4.6

My package.json file:

{
   "name":"coursetro-eth",
   "version":"1.0.0",
   "main":"index.js",
   "scripts":{
      "dev":"webpack-dev-server --config build/webpack.dev.conf.js",
      "publish":"ngc -p tsconfig-aot.json",
      "test":"echo \"Error: no test specified\" && exit 1"
   },
   "author":"",
   "license":"ISC",
   "description":"",
   "dependencies":{
      "web3":"github:ethereum/web3.js"
   },
   "devDependencies":{
      "lite-server":"^2.3.0",
      "webpack":"^4.6.0",
      "webpack-cli":"^2.0.15",
      "webpack-dev-server":"^2.11.2",
      "webpack-validator":"^2.3.0"
   }
}

What is this error about?

  • Can you check if it is under node_modules? Perhaps you need to run `npm install` before starting your app. – Guido Apr 29 '18 at 10:27
  • Thanks a lot for answering, I ran npm install but it didn't change anything. – Siberian Sim Apr 29 '18 at 11:19
  • I have seen this interesting post but it didn't solve my problem neither. https://stackoverflow.com/questions/40379139/cannot-find-module-webpack-bin-config-yargs – Siberian Sim Apr 29 '18 at 11:24
  • Pleas add your package.json file to the question – Guido Apr 29 '18 at 17:38
