[React 오류 ] npx webpack이 안되는데요?

Error: Cannot find module 'webpack-cli/package.json'
Require stack:
- /Users/.npm/_npx/92619/lib/node_modules/webpack/bin/webpack.js
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:880:15)

  code: 'MODULE_NOT_FOUND',
  requireStack: [

  ]
}

이런 오류가 난다면 

당황...조금만 하고(쒸이익)

 

일단 설치한 webpack-cli파일등이 있다면 uninstall해준 후 다시 깔아주면 된다. 

 

1. npm uninstall -D webpack webpack-cli  

2. npm install -D webpack webpack-cli

 

나는 webpack이 패키지 제이슨에 깔려있지 않았어서 webpack-cli만 지우고 다시 둘다 깔아줌!!!
