尝试使用“ npm start”启动React应用时遇到ELIFECYCLE错误

问题描述

尝试启动我的React应用时遇到以下错误。

 events.js:174
     throw er; // Unhandled 'error' event
     ^ Error: spawn powershell.exe ENOENT
     at Process.ChildProcess._handle.onexit (internal/child_process.js:240:19)

 /root/.npm/_logs/2020-09-15T14_43_41_420Z-debug.log

我在Windows 10系统上的VSCODE中使用bash终端。

可能相关的其他信息：

• 用于安装create-react-app的命令-> npm install create-react-app
• 用于创建新的React应用的命令-> npx create-react-app my_app
• NPM版本-> 6.14.4

请注意，关于React我是一个完整的初学者。将不胜感激对此提供的任何投入。谢谢！

解决方法

您可以提供更多信息吗？您在使用yarn start吗？

还有一个注意事项-如果使用npx，则不必安装create-react-app。该答案解释了npx和npm-https://stackoverflow.com/questions/50605219/difference-between-npx-and-npm#:~:text=npx%20is%20a%20npm%20package,it%20in%20a%20single%20step之间的区别。
