我仍然无法最终理解 apache 如何理解它现在应该运行哪个版本的 python。
在 virtualenv 我只安装 python3.2 ，然后我把这样的代码放在 wsgi 包装器上：
# -*- coding: utf-8 -*-
#!/virtualenvs/simpleboard/bin/python
import os, sys, site
my_virtualenv_path = "/virtualenvs/simpleboard/lib/python3.2/site-packages/"
# Add it to your PYTHONPATH
sys.path.insert(0, my_virtualenv_path)
site.addsitedir(my_virtualenv_path)
sys.path.insert(0, os.path.dirname(__file__))
sys.path.insert(0, '/www/django/simpleboard/simpleboard')
sys.path.insert(0, '/www/django/simpleboard')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "simpleboard.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
最后我在我的类代码的头部添加了这个标签，但 apache 仍然运行 2.7
Exception Location: /www/django/simpleboard/account/views.py in rescale, line 386

Python Version: 2.7.3
Python Path:

如您所见，它运行 2.7 版本并因此出现回溯错误
