Javascript Heroku-部署React/Express应用程序并获取'；无法加载资源'；在控制台中请求chunk.js文件时

在Heroku上构建并部署React应用程序后，我在控制台中收到这些错误

Refused to apply style from 'https://radiant-tor-66940.herokuapp.com/index.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

index.js

文件位于我的Heroku服务器上的

/client/build/

中。这是我的Express服务器发送的文件。服务器正在发送此

index.html

文件，但文件本身找不到所需的资源

这会导致加载空白应用程序的问题。出于某种原因，

index.html

在

/client/build/static/js

中找不到

chunk.js

文件。它们肯定在那里，我可以通过heroku运行bash和检查目录来确认

在浏览器中查看

index.html

文档时，我可以在底部看到脚本标记调用

/static/js

中的

chunk.js

文件的位置：

这就是应用程序的root

server.js
文件中，我在这篇文章中没有包括这个文件

最初它是
express.static（path\u join（\u dirname，'/client/build'））

它必须是：
express.static（path\u join（\uu dirname，../client/build'））

这是因为我的
server.js
文件位于
/server
中，它试图在
/server
中查找
/client/build
，而不是在Heroku上查找根应用程序目录
