使用“pip”更新 pyOpenSSL 和 pandas 失败，并显示“TypeError：resolve() 获得意外的关键字参数“replace_conflicting””

当我尝试更新或安装任何版本时pandas or pyOpenSSL（对于任何实例sudo pip --[un]install|update [--no-use-wheel] [pandas|pyOpenSSL|xattr|stevedore], using pip1.5.4）我得到：

Command python setup.py egg_info failed with error code 1 in /private/tmp/pip_build_root/pandas
Storing debug log for failure in /Users/Rax/Library/Logs/pip.log
...
TypeError: resolve() got an unexpected keyword argument 'replace_conflicting'

为什么我会收到此错误？我可以采取什么措施来避免它？

操作系统 10.9.2； Python 2.7.5；setuptools 3.4.3.

FWIW，我可以安装pandas在虚拟环境中成功。如果我将其从那里复制回出现此错误的环境并运行nosetests pandas I get:

OK (SKIP=330)

这也是我在虚拟环境中运行测试时得到的结果。

A 可能的原因是存在多个版本的setuptools，Python 路径上的旧版本比新版本早。为了安装目的，可以通过开始调用来暂时克服这个问题pip with

PYTHONPATH=/PATH_TO_YOUR_CURRENT_PACKAGES/site-packages pip ...

您可以通过执行来确认是这种情况

import pkg_resources
pkg_resources.__file__

在 Python 中并注意到pkg_resources.pyc返回的是not在当前站点包的位置。

在某些情况下，这也可以通过确保pkg_resources.pyc在您的站点包目录中执行，而不是在您的系统包目录中（例如，通过删除后者）。
