为什么我的Django模块缺失？

Question

我发现了一个错误：

ImportError at/
No module named lxml 
Request Method: GET 
Request URL: http://www.myurl.com/ 
Django Version: 1.2.1 
Exception Type: ImportError 
Exception Value:  
No module named lxml 
Exception Location: /mypath/project/app/views.py in <module>, line 4 
Python Executable: /usr/bin/python 
Python Version: 2.5.2 
Python Path: ['/usr/local/dh/passenger/lib/phusion_passenger/wsgi', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/Numeric', '/usr/lib/python2.5/site-packages/PIL', '/var/lib/python-support/python2.5', '/usr/lib/site-python', '/home/mysite/mysite.com', '/home/mysite/local/lib/python2.5/site-packages']

我修改的路径，显然的名字，但我home/mysite/local/lib/python2.5/site-packages folder内，我有lxml-2.3beta1-py2.5-linux-x86_64.egg，怎么让Django中找不到它？

Answer 1

因为.egg不在sys.path。如果你已经将它安装到自定义路径中，那么你需要自己添加它。
