Question

由于我的shell脚本中的错误，我不小心删除了/ usr目录，然后从这个虚拟机的早期备份恢复，然后重新安装了它的所有包，现在几乎一切正常，除了：

Answer 1

这是一个pip错误。 pip团队遇到already closed此问题，因此在安装其他任何内容之前，您可以手动安装特定版本的pytz：

pip install pytz==2013k

或更方便：

pip install --pre pytz

根据问题讨论，pip对pytz版本控制感到困惑，最新的release版本被错误地解释为prerelease。使用--pre选项，您可以强制安装prerelease版本，实际上是release。

然后，您将能够安装其他依赖于pytz的包。

意外删除/ usr后，pip找不到依赖项
