pythonbrew 没有被 mod_wsgi 文件接收，配置如下：
import os
import sys
import site
site.addsitedir('/home/bharal/.pythonbrew/pythons/Python-2.7.2/lib/python2.7/site-packages')
sys.path.append ('/home/bharal/public_html/dumpstown')
os.environ['DJANGO_SETTINGS_MODULE'] = 'dumpstown.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
我想使用的pythonbrew版本的python位于：
/home/bharal/.pythonbrew/pythons/Python-2.7.2/lib/python2.7/site-packages
我的 pythonbrew 安装在这里：
/home/bharal/.pythonbrew/
我如何告诉 mod_wsgi 使用这个版本 (2.7.2) 而不是 ubuntu (2.6) 附带的默认 python 版本？
当我运行我的服务器时，我收到如下错误：

从日志中可以看出，服务器仍在查看 python 2.6！为什么？我已经启动了 pythonbrew，所以当我输入时，python我可以看到版本是 2.7.2，并且我需要的所有设置和包都是可导入的！
更新如下面的答案所示，mod_wsgi不在乎我告诉它使用哪个 python - 事实上，我不能告诉它使用任何特定的 python。这样做的唯一方法是下载一个未编译的 wsgi 文件，使用我想要的特定 python 版本进行编译，然后使用已编译的 wsgi。
如果您愿意，请参阅我的另一个问题Error: Command failed with rc=65536 python and mod_wsgi了解一些步骤和指向 tutes 的链接。最后我没有针对 2.7 进行编译（我的 2.6 很好，让 pythonbrew 编译工作太难了）
