每当我尝试使用pip时,我都会收到错误消息.例如:

$ sudo pip install gevent-websocket

Traceback (most recent call last):  
File "/usr/local/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2675, in <module>
parse_requirements(__requires__), Environment()
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 552, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==0.8.1

我觉得很想把值改成pip == 0.8.2 ..但我不觉得处理"黑客攻击"安装的后果......我正在运行python 2.7并且pip是0.8.2版本.

当我尝试使用pip时,我遇到了这个错误:

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 9, in <module>
    load_entry_point('pip==1.0.2', 'console_scripts', 'pip')()
  File "/usr/local/lib/python2.6/dist-packages/distribute-0.6.21-py2.6.egg/pkg_resources.py", line 337, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/local/lib/python2.6/dist-packages/distribute-0.6.21-py2.6.egg/pkg_resources.py", line 2281, in load_entry_point
    return ep.load()
  File "/usr/local/lib/python2.6/dist-packages/distribute-0.6.21-py2.6.egg/pkg_resources.py", line 1996, in load
    raise ImportError("%r has no %r attribute" % (entry,attr))
ImportError: <module 'pip' from '/usr/lib/pymodules/python2.6/pip/__init__.pyc'> has no 'main' attribute

显然,我对破坏了pip的系统做了一些改变.但我不知道它是什么.什么可能导致上述例外？

编辑:

我能猜到的是,今天早上,我创建了一个virtualenv,通过运行安装自己编写的包:

python setup.py安装

在那种环境中.

顺便说一句,我确实尝试通过运行get-pip.py来重新安装pip,但是没有用

yolk -U最近运行我注意到pip需要从1.2.1升级到1.4.1并且尽职尽责地尝试升级它

pip install --upgrade pip

虽然yolk -U再次运行似乎确认升级成功(pip不再列为过时),但这会生成错误消息
