从repo中删除.pyc文件时出现Django错误

Question

几个小时以来，我一直在摸不着头脑。

我很乐意在测试服务器上拉我回购。该项目有很多提交。我想清理我的repo中的所有.pyc文件，所以在我的主人中删除它们并将* .pyc添加到.gitignore。这是对最后一次提交的唯一更改。

现在，当我拉到测试服务器时，Django导入失败。然而，该模块在那里，除了.pyc expunging之外没有其他变化。所以这个错误基本上是假的。

如果我重新添加.pyc文件，它会再次愉快地工作。

任何人都可以对此有所了解吗？

Answer 1

事实证明，__init__.py已经将其作为.gitignore的论据。所以我的所有模块都是在没有__init__.py的情况下提交的。虽然__init__.pyc文件仍然存在，但这些文件必须被用作“后备”（我没有意识到python会这样做）所以我的错误被混淆了。我很糟糕，但我学到了很多好的教训。

要清理Django .pyc文件，请执行终端中的一个或所有命令：

$ python manage.py cleanup
$ pyclean .
$ find . -name "*.pyc" -exec rm -f {} \;
$ find . -name \*.pyc -delete
$ python manage.py clean_pyc
