我还尝试在我的usr/local/lib/python2.7/dist-packages/setuptools/archive_util.py.中将"from pkg_resources import ensure_directory，ContextualZipFile“更改为"from pkg_resources import ensure_directory然而，我得到了错误

NameError: global name 'ContextualZipFile' is not defined我也尝试过直接导入pkg_resources，但仍然找不到ContextualZipFile。我得到了错误：
NameError: global name 'ContextualZipFile' is not defined我使用python version = 2.7.13和pip version = 9.0.1
我也是在虚拟环境中这样做的。

这是一个相当糟糕的技巧，但我刚刚注释掉了导入，easy_install似乎工作得很好。将相应的行更改为：
from pkg_resources import ensure_directory#, ContextualZipFile注意:这是一个系统文件，所以您必须使用sudo权限来更改它。您可以使用：sudo vim filename来完成此操作。
这不是一个很好的修复方法，但是如果你需要让它在短时间内工作，这应该能起到作用。希望这能有所帮助！

这似乎是一个常见的错误https://github.com/pypa/setuptools/issues/252
最简单的方法是使用另一种方法，比如: yum -y install python-pip
