当我尝试 pip freeze（或 pip freeze > requirements.txt）时，我遇到了这个错误：

$ pip freeze
Error [Errno 20] Not a directory: '/usr/local/lib/python2.7/dist-packages/flaskr-0.0.0-py2.7.egg' while executing command git rev-parse
Exception:

    raise child_exception
OSError: [Errno 20] Not a directory: '/usr/local/lib/python2.7/dist-packages/flaskr-0.0.0-py2.7.egg'

我在安装某些软件包时没有错误。我暂时不使用 virtualenv。请对此错误有所了解？

谢谢。 F.

【解决方案1】：

这只是 Flaskr 的一个问题（我不知道它为什么在这里......）所以，我只是这样做：

sudo pip uninstall Flaskr

而且，它已经完成了。
