在全新安裝的ActivePython-2.6上，pip提供了導入錯誤

我在虛擬機上安裝了Cent OS，它附帶Python 2.4開箱即用。我需要安裝Python 2.6，所以我從ActivePython安裝了一個單獨的Python二進制文件，它將自己安裝在不同的目錄中。當我運行PIP（/opt/ActivePython-2.6/bin/pip）我得到這個錯誤：在全新安裝的ActivePython-2.6上，pip提供了導入錯誤

# pip 
Traceback (most recent call last): 
    File "/opt/ActivePython-2.6/bin/pip", line 9, in <module>

    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

    import urllib2

     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

我以前從未見過這樣的錯誤，我不明白爲什麼它會嘗試調用_md5當庫只是「MD5」。當我嘗試將_md5.py鏈接到md5.py時，我得到的錯誤是ImportError: No module named _md5。

_md5是md5.py導入的基礎編譯C庫;這裏使用C庫的包裝器來提高速度。 – 2010-12-03 22:42:59

在/opt/ActivePython-2.6中找到_md5.so並在其上運行ldd。是啊。

安裝EPEL，通過yum安裝python26，玩得開心。
