導入matplotlib.pyplot時出錯

Question

當我運行import matplotlib.pyplot as plt ，我收到以下錯誤消息：

---------------------------------------------------------------------------

我的/Library/Python/2.7/site-packages/setuptools.pth是這樣的： /Library/Frameworks/EPD64.framework/Versions/7.3/Python 。 我的/Library/Python/2.7/site-packages/easy-install.pth如下：

import sys; sys.__plen = len(sys.path)
./pip-1.2.1-py2.7.egg
/Library/Frameworks/EPD64.framework/Versions/7.3/Python
./pudb-2012.3-py2.7.egg
./Pygments-1.5-py2.7.egg
./urwid-1.0.2-py2.7-macosx-10.8-intel.egg
import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new)

我應該如何正確導入matplotlib.pyplot ？ 我已經安裝了自制軟件，正在運行Enthought Python Distribution，並且正在運行OSX。

我修好了它！ 我做的是以下內容：我刪除了（在備份后）我系統的site-packages文件夾（ /Library/Python/2.7/site-packages ）中的matplotlib文件夾。
