⠋ building schema
npm ERR! code ELIFECYCLE

npm ERR! Exit status 1

npm ERR! Failed at the react-website@0.0.1 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\enssel\AppData\Roaming\npm-cache\_logs\2019-07-11T02_36_02_851Z-debug.log

Removed cache and reinstalled npm package, but not effective.

I did as follows. npm start dev

这是一个冲突的端口。只需更新您的 webpack.config.js 并手动设置端口。

   devServer: {
     historyApiFallback: true,
     contentBase: './',
     port: 3000 // <--- Add this line and choose your own port number
   }
