wsgi和虚拟环境
我正在用apache，mod_wsgi，virtual env设置Django
我有一个虚拟的env ，我想在这里使用：[Missleading name - long story！] / home / andy / Dev / python / async-mongo /
我下载了mod_wsgi并以root身份用virtual_env进行了编译
./configure --with-python = / home / andy / Dev / python / async-mongo / bin / python
我以root身份运行：
进行安装
我在http.conf中设置了WSGIPythonHome＆Path
WSGIPythonHome /home/andy/dev/python/async-mongo/
WSGIPythonPath /home/andy/dev/python/async-mongo/lib/python2.6/site-packages
LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so
我想我遵循http://code.google.com/p/modwsgi/wiki/VirtualEnvironments上的说明
当我运行“Hello World”应用程序时，它可以工作
def application(environ, start_response):
status = '200 OK'
output = 'Hello World!'
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
当我尝试导入模块时失败 ：
import sys; raise Exception(sys.path)
def application(environ, start_response):
status = '200 OK'
output = 'Hello World!'
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
print >> sys.stderr, 'sys.prefix = %s' % repr(sys.prefix)
print >> sys.stderr, 'sys.path = %s' % repr(sys.path)
return [output]
我在apache日志中看到的错误是：
[Fri Mar 30 15:09:53 2012] [notice] Apache / 2.2.20（Ubuntu）mod_wsgi / 3.3配置Python / 2.6.7 - 恢复正常操作

我猜在某处我仍然引用旧的系统级python，但我不明白在哪里。 我怎样才能解决这个问题？
你在这里提出一个例外：
import sys; raise Exception(sys.path)
摆弄sys.path的地方在your_application.wsgi。 我不认为编译指向virtualenv python二进制文件的mod_wsgi是一个好主意，virtualenv的重点是灵活性（例如，django的多个版本在同一台机器上播放不错）。
我对django，apache，wsgi和virtualenv的看法是这样的一个my_application.wsgi文件：
import os
import sys
import site
# Backup sys.path
prev_sys_path = list(sys.path)
# Add virtual environment to site directories:
site.addsitedir('/var/lib/python-environments/my_env/lib/python2.6/site-packages')
# settings.py sitting at /path/to/apps/my_application
os.environ['DJANGO_SETTINGS_MODULE'] = 'my_application.settings'
sys.path.append('/path/to/apps')
# start the trick
sys.path.extend([
'/var/lib/python-environments/my_env/lib/python2.6/site-packages',
'/var/lib/python-environments/my_env/lib/python2.6/site-packages/django/contrib/admindocs',
])
# Reorder syspath
new_sys_path = [p for p in sys.path if p not in prev_sys_path]
for item in new_sys_path:
sys.path.remove(item)
# Make sure virtual env is first
sys.path[:0] = new_sys_path
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
