python - 使用 'pip' 更新 pyOpenSSL 和 pandas 失败，出现 "TypeError: resolve() got an unexpected keyword argument ' replace_conflicting'"

Question

当我尝试更新或安装任何版本的 pandas 或 pyOpenSSL(使用 sudo pip --[un]install|update [- -no-use-wheel] [pandas|pyOpenSSL|xattr|stevedore]，使用 pip 1.5.4) 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'

为什么会出现此错误，我该如何避免？

操作系统 10.9.2； Python 2.7.5； 设置工具 3.4.3.

FWIW，我可以在虚拟环境中成功安装 pandas。如果我将它从那里复制回出现此错误的环境并运行 nosetests pandas 我得到:

OK (SKIP=330)

如果我在虚拟环境中运行测试，这也是我得到的结果。

A likely cause setuptools 存在多个版本，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 pip 来暂时克服此问题

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

你可以通过执行来确认是这种情况

import pkg_resources
pkg_resources.__file__

在 Python 中并注意返回的 pkg_resources.pyc 不在您当前站 pip 包的位置。

在某些情况下，这也可以通过确保执行站 pip 包目录中的 pkg_resources.pyc 来纠正，而不是系统包目录中的那个(例如，通过删除后者) .
