Question

我使用CRA创建了一个新的react应用。启动开发服务器后，它将引发错误并退出。

Starting the development server...

      throw er; // Unhandled 'error' event

react-scripts版本3.0.1避免使用“ npm start”。我尝试降级到2.1.8版，但效果很好。但是我不想每次都降级版本以使我的应用正常工作。 I tried following the similar case，但没有帮助。遇到此问题的其他任何人，请帮助解决。

如果您尝试了this，但对您不起作用，那么这可能是一个反应脚本问题，因此要解决此问题，请尝试以下操作：

remove node_modules and lock files
edit package.json so the version of react-scripts is "2.1.8"
npm install
npm start
