它显示了，并且显示不正常。

The project was built assuming it is hosted at the server root.
You can control this with the homepage field in your package.json.
For example, add this to build it for GitHub Pages:
"homepage" : "http://myname.github.io/myapp",
The build folder is ready to be deployed.
You may serve it with a static server:
yarn global add serve
serve -s build

客户端文件夹是在相同的层次结构中创建的。
即使您查看git log，服务器似乎也能正常工作，所以我认为获取react的index.html并不是很好。
