npm run dev - webpack-cli 에러

적어주신대로 입력해봤는데 에러가 납니다.. configuration 타입에 문제가 있는건가요?

아래는 터미널에서 npm run dev 했을 때 에러이고,

[webpack-cli] Failed to load 'C:\Users\user\Desktop\coding\sleact\client\webpack.config.ts' config

devServer 안에 바로 publicPath를 적지 말고 static 객체를 만들고 그 안에 publicPath 해야합니다.

devServer: {

  static: { publicPath: ... },

  다른거

}
