升级pip后出现DistributionNotFound错误 [英] DistributionNotFound error after upgrading pip

问题描述

在阅读有关virtualenv的信息时此处，我意识到我没有1.3点以上的知识，所以我跑了pip install --upgrade pip，现在当我运行pip --version时，我得到以下信息:

In reading about virtualenv here I realized I didn't have pip 1.3+, so I ran pip install --upgrade pip and now when I run pip --version i get the following:

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/distribute-0.6.34-py2.7.egg/pkg_resources.py", line 2807, in <module>
    parse_requirements(__requires__), Environment()
  File "/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/distribute-0.6.34-py2.7.egg/pkg_resources.py", line 594, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==1.2.1

如果有帮助，或者完全相关，那么我的$PATH看起来像这样:

If it helps, or is at all relevant, my $PATH looks like this:

/usr/local/bin:/usr/local/share/python:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin

另外，which pip给了我/usr/local/bin/pip.

不确定如何处理该错误.谢谢.

Not sure what to do about the error. Thanks.

推荐答案

残酷的方式:

假设您在Mac上使用自制软件(因为我看到了/usr/local/Cellar)，我建议

The brutal way:

Assuming you are using homebrew for Mac (because I see /usr/local/Cellar), I suggest to

• 删除(或备份)/usr/local/lib/python2.7和
• brew rm python && brew install python.

• remove (or backup) /usr/local/lib/python2.7, and
• brew rm python && brew install python.

这肯定会与python一起安装pip 1.3.3.您的分配也将为0.6.35.

This will definitely install pip 1.3.3 alongside of python. Your distribute will also be 0.6.35.

从/usr/local/lib/python2.7/site-packages中删除:

• easy-install.pth
• pip-1.2.1-py2.7.egg 或您拥有的其他pip版本.
• distribute-0.6.34-py2.7.egg 或其他版本

• easy-install.pth
• pip-1.2.1-py2.7.egg or other versions of pip you have.
• distribute-0.6.34-py2.7.egg or other versions

然后，brew rm python && brew install python.这将使来自brew和已安装东西的所有其他绑定保持不变. Python，pip和distribution将被最新版本取代.

Then, brew rm python && brew install python. This will leave all your other bindings from brew and installed stuff intact. Python, pip and distribute will be replaced with up-to-date versions.

请确保您在/Library/Python/2.7/site-packages中没有分发或设置工具或pip.该目录已在所有python 2.7版本(从brew或从OS X发行)中重新使用，并且会干扰Homebrew已安装的pip/distribute.

Please check that you don't have a distribute or setuptools or pip located in /Library/Python/2.7/site-packages. That dir is re-used by all python 2.7 versions (brewed or from OS X) and will interferre with the pip/distribute already installed by Homebrew.
