在Mac OS Yosemite上安装后获取pip版本时出错

Question

我在Mac上安装了python2.7.6，也是pip。但是当尝试获取pip版本或运行它时，它有错误。

这是我的Mac的输出：

$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
$ which pip
/Library/Frameworks/Python.framework/Versions/2.7/bin/pip
$ python -V
Python 2.7.6
$ pip --version
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2793, in <module>
    working_set.require(__requires__)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 673, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 576, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==1.3.1

知道吗？

此错误是因为您的 Mac OSX python 完好无损，但您已从库中删除了 Python 文件夹。只需在 ~/.bash_profile 中为 Mac OSX python 设置路径，它就会得到解决。
