在OS X 10.8升级后,Python pip被破坏

Question

升级到Mac OS X 10.8(Mountain Lion)并在尝试呼叫时出现以下错误$ 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重新安装(使用http://www.pip-installer.org/en/latest/installing.html#using-the-installer和easy_install),但是没有工作,得到了相同的错误.

现在尝试以下内容:调用$ sudo pip和上述错误消失.奇怪的是,在上面的错误消息中找不到的目录指向/ System/Library/...而python安装是(new？)在/ Library/Frameworks/..中查找:

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

任何想法如何摆脱sudo？

Answer 1

用于easy_install将您更新pip到最新版本:

sudo easy_install -U pip

另外,请确保XCode安装了最新版本(版本4.4)Command Line Tools.

Answer 2

这适合我

rm -f /usr/local/bin/easy_install
brew reinstall python
pip install --upgrade setuptools
pip install --upgrade pip

Answer 3

我有一个类似的错误,除了sudo pip不起作用.我正在使用python的"brew"安装(符号链接到/ usr/local/bin),发现问题是pip和easy_install文件中的shebangs硬编码#!/usr/bin/python而不是#!/usr/local/bin/python,所以使用系统python版本而不是brew版本.

干杯,汤姆
