react 项目 npm run start 报错

There might be a problem with the project dependency tree.

It is likelynota bug in Create React App, but something you need to fix locally.

Thereact-scriptspackage provided by Create React App requires a dependency:

  "webpack": "4.41.0"

Don't try to install it manually: your package manager does it automatically.

However, a different version ofwebpackwas detected higher up in the tree:

  /Users/macbook/node_modules/webpack (version: 4.40.2) 

Manually installing incompatible versions is known to cause hard-to-debug issues.

If you would prefer to ignore this check, addSKIP_PREFLIGHT_CHECK=trueto an.envfile in your project.

That will permanently disable this message but you might encounter other issues.

解决方法

创建一个 .env 文件 SKIP_PREFLIGHT_CHECK=true 添加这句代码，在npm start就好了。
