Question

我正在使用apache，mod_wsgi，虚拟环境

设置Django

我想在这里使用虚拟环境：[误导性名称 - 长篇故事！] /家庭/安迪/开发/蟒/异步-蒙戈/

我下载 mod_wsgi 并使用virtual_env作为root进行编译

./ configure --with-python = / home / andy / Dev / python / async-mongo / bin / python

我以root身份跑：

make install

我设置了WSGIPythonHome＆amp; http.conf中的路径

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

我想我按照http://code.google.com/p/modwsgi/wiki/VirtualEnvironments

上的说明操作了

当我运行'Hello World'应用程序时，它有效

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

我猜不到某种程度上我还在引用旧的系统级python，但我无法理解在哪里。我该如何解决这个问题？

Answer 1

你在这里提出例外：

import sys; raise Exception(sys.path)

Answer 2

摆弄sys.path的地方是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，有几个版本的django在同一台机器中运行良好）。

我对django，apache，wsgi和virtualenv的看法是像这样的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()

Django，mod_wsgi和虚拟环境
