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

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.
I don't solve this problem
Error: Cannot find module 'webpack-cli/bin/config-yargs'
The code for 'package.json' is as follows.
"dependencies": {
"#vue/cli-plugin-babel": "^3.5.1",
"config": "^3.0.1",
"vue": "^2.5.2",
"vue-router": "^3.0.1"
},

"vue-jest": "^1.0.2",
"vue-loader": "^13.3.0",

"webpack-bundle-analyzer": "^3.3.2",
"webpack-cli": "^3.3.10",
"webpack-dev-server": "^3.1.14",

},

Answer 1

You could try changing webpack-dev-server to webpack serve in your npm run script inside package.json

Answer 2

For some reason the webpack team changed the command to webpack serve
Change your package.json:
"start": "webpack serve"
Ref: https://github.com/webpack/webpack-dev-server/issues/2759
The version I am using:
"webpack": "^5.10.0",
"webpack-cli": "^4.2.0",
"webpack-dev-server": "^3.11.0"

Answer 3

To fix it just do 2 things.
Install
npm i webpack-cli #webpack-cli/init
Add this to your package.json:
"scripts": {
"start": "webpack-cli serve --mode development"
},
Done!

Answer 4

I agree that you have to upgrade from webpack 3 to 4, but specifically these are the steps I had to do, first, because webpack-cli has been split out into a separate package:
$ npm install webpack webpack-cli --save-dev
As explained here: https://webpack.js.org/guides/getting-started/#basic-setup

Answer 5

Delete package-lock.json file. Change following in package.json.
"webpack": "^4.32.2",
"webpack-cli": "^3.3.0",
"webpack-dev-server": "^3.11.0"
Run npm install

Answer 6

Change webpack-dev-server to webpack serve in package.json file.
e.g.:
"scripts": { "start": "webpack serve --mode development --open" },
It worked for me! ;-)

Answer 7

"scripts": {
"start": "webpack serve --mode development",
"build": "webpack --mode production"
},
Run: npm run start or npm start now

Answer 8

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 9

webpack core team says that form version 3+ the compatibility will foucs on webpack 4
so I think you need also to update webpack 3 to webpack 4
this doc may help you to achieve that

Answer 10

You have to check to find out the latest versions of webpack, webpack-cli and webpack-dev-server and when you have that information edit package.json to reflect those versions and run yarn install --check-files Then you'll have to start the webpack-dev-server with the command "npx webpack serve"
