删除了__pycache__和__init__.py

Question

• Django 1.6
• Ubuntu 12.04
• Python 3.2.3

意外删除了Django应用的__pycache__文件夹＆amp;它的__init__.py文件，它崩溃了Django。当我python3 manage.py runserver时，即使应用程序的目录存在且所有文件都在其中（除了我删除的文件）之外，它立即声称没有名称​​ agepct 的模块。我清空垃圾桶，所以我无法取回文件。有没有办法让应用程序再次工作，而不是从头开始重新创建整个应用程序？

这是我尝试runserver时吐出的追溯：

__pycache__目录是字节编译文件的缓存，将在导入包时重新构建。

另一方面，__init__.py文件是使目录成为模块的原因。如果它最初为空，只需在agepct目录中重新创建它以使导入再次起作用。请注意，__init__.py 不在<{1}}目录中。

如果__pycache__不仅仅是一个空的'make this a package'文件，那么你必须从头开始重新创建该代码或从备份中恢复该文件。
