意外删除了 Django 应用程序的__pycache__文件夹及其__init__.py文件，导致 Django 崩溃。当 I 时python3 manage.py runserver，它会立即声称没有名为agepct的模块，即使应用程序的目录存在并且所有文件都在其中（我删除的文件除外）。我清空了垃圾箱，所以我无法取回文件。除了从头开始重新创建整个应用程序之外，有什么方法可以让应用程序再次运行？

这是我尝试时吐出的回溯runserver：

该__pycache__目录是字节编译文件的缓存，将在您导入包时重新构建。

__init__.py另一方面，文件使目录成为模块。如果它最初是空的，只需在agepct目录中重新创建它，导入即可再次工作。请注意，它不会__init__.py在目录中。__pycache__

如果__init__.py不仅仅是一个空的“将此作为一个包”文件，那么您必须从头开始重新创建该代码或从备份中恢复该文件。
