it needs to be installed alongside webpack to use the CLI

webpack-cli needs to be installed at the same time as webpack to take effect. Remember! Install

at the same time

yarn add webpack-cli webpack- D

encountered the same problem. I don't know if you also use webpack4?.
my solution is to add the configuration to the config configuration file: mode: 'development' or mode:' production'

module.exports={
    //
    mode: 'development',
    devServer: {
        //
        
    } 
}

mode is a new configuration item for webpack4.
you can try. The
command line with arguments-- mode development or-- mode production should also work.

reference:

package.json version is as follows:

"webpack": "^5.17.0",
"webpack-cli": "^4.4.0",
"webpack-dev-server": "^3.11.2"

later on github issues find a solution

1, install
npm I webpack-cli @ webpack-cli/init
2, Adjust package.json

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

delete node\ _ modules

yarn add webpack webpack-cli -D

Edit package.json

"scripts":{
"start":"webpackserve"
}

yarn start

try not to use npm
