我有一个React应用程序，大多数文件都是在命令调用后正常更新/构建的，然后进行后续的文件更改。特别是除了一个文件之外的所有文件，该文件只生成一次。初始编译和FIRST文件更改。之后，webpack停止构建这个ONE文件。此目录中的所有其他文件构建良好。

非常感谢您的帮助。我认为测速插件造成了问题，所以我暂时删除了包装器。
经过数小时的搜索。。。问题出在我的进口声明上。我的名字相同，但大小写不正确。
文件名：MyComponent.js
错误import MyComponent from "./myComponent
正确imoprt MyComponnent from "./MyComponent
