我在虚拟机上安装了 Cent OS，它自带 Python 2.4。我需要安装 Python 2.6，所以我从 ActivePython 中安装了一个单独的 python 二进制文件，它自己安装在不同的目录中。当我运行 pip ( /opt/ActivePython-2.6/bin/pip) 时，我收到此错误：

# pip
Traceback (most recent call last):
  File "/opt/ActivePython-2.6/bin/pip", line 9, in <module>
    load_entry_point('pip==0.8.1', 'console_scripts', 'pip')()
  File "/opt/ActivePython-2.6/lib/python2.6/site-packages/pkg_resources.py", line 305, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/opt/ActivePython-2.6/lib/python2.6/site-packages/pkg_resources.py", line 2244, in load_entry_point
    return ep.load()
  File "/opt/ActivePython-2.6/lib/python2.6/site-packages/pkg_resources.py", line 1954, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
  File "/opt/ActivePython-2.6/lib/python2.6/site-packages/pip/__init__.py", line 10, in <module>
    from pip.basecommand import command_dict, load_command, load_all_commands, command_names
  File "/opt/ActivePython-2.6/lib/python2.6/site-packages/pip/basecommand.py", line 11, in <module>
    import urllib2
  File "/opt/ActivePython-2.6/lib/python2.6/urllib2.py", line 93, in <module>
        import hashlib
  File "/opt/ActivePython-2.6/lib/python2.6/hashlib.py", line 136, in <module>
    md5 = __get_builtin_constructor('md5')
  File "/opt/ActivePython-2.6/lib/python2.6/hashlib.py", line 63, in __get_builtin_constructor
    import _md5
ImportError: No module named _md5

我以前从未见过这个错误，我不明白为什么当库只是'md5'时它会尝试调用_md5。当我尝试将 _md5.py 符号链接到 md5.py 时，我得到了同样的错误，但是ImportError: No module named _md5.

找到_md5.so并/opt/ActivePython-2.6运行ldd它。是的。

安装EPEL，python26通过 yum 安装，玩得开心。
