Error: Cannot find module 'webpack/bin/config-yargs' when install webpack 4

Question

When I updated webpack from version3 to 4 in my work project, and try to run server (npm run server), I have an error

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

To install new version I use

yarn add webpack webpack-cli --dev

Here is my package.json scripts

"server": "webpack-dev-server  --config webpack.dev.js",
"build": "webpack  --config webpack.prod.js"

Answer 1

Try:

"server": "webpack serve --config webpack.dev.js"
