[react]react启动报错

 7. Try running npm ls eslint in your project folder.
     This will tell you which other package (apart from the expected react-scripts) installed eslint.


If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That would permanently disable this preflight check in case you want to proceed anyway.


P.S. We know this message is long but please read the steps above :-) We hope you find them helpful!

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

You can now view project01 in the browser.

Note that the development build is not optimized.
To create a production build, use yarn build.    





解决办法：
在根目录上加一个.env文件
文件里只有一句代码：SKIP_PREFLIGHT_CHECK=true
