OS X 10.8升级后Python点破 [英] Python pip broken after OS X 10.8 upgrade

问题描述

进行了Mac OS X 10.8(Mountain Lion)的升级，并在尝试调用$ pip时出现以下错误:

Made the upgrade to Mac OS X 10.8 (Mountain Lion) and get now the following error when trying to call $ pip:

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 2603, in <module>
    working_set.require(__requires__)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 565, in resolve
    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: pip==1.1

更新:尝试通过再次执行安装过程来重新安装(使用 http: //www.pip-installer.org/zh-CN/latest/installing.html#using-the-installer 和easy_install)，但没有成功，出现了相同的错误.

Update: Tried to reinstall by doing the install procedure again (with http://www.pip-installer.org/en/latest/installing.html#using-the-installer and easy_install), but didn't work, got the same error.

现在尝试以下操作:调用$ sudo pip，以上错误消失.奇怪的是，在上述错误消息中找不到的目录指向/System/Library/...，而python安装是(new?)，可以在/Library/Frameworks/..中找到:

Tried now the following: Calling $ sudo pip and the above error disappears. Strange is, that the directories which could not befound in the above error message point to /System/Library/... while the python installation is (new ?) to find in /Library/Frameworks/..:

$ which python
/Library/Frameworks/Python.framework/Versions/Current/bin/python

有人知道如何摆脱sudo吗?

Any idea how to get rid of the sudo?

推荐答案

使用easy_install将pip更新到最新版本:

Use easy_install to update your pip to the latest version:

sudo easy_install -U pip

还要确保安装了最新的XCode(版本4.4)和Command Line Tools.

Also make sure you have the lastest XCode installed (ver 4.4) with Command Line Tools.
