Django，mod_wsgi和虚拟环境 [英] Django, mod_wsgi and virtual env

问题描述

我正在使用apache，mod_wsgi，virtual env设置Django

我有一个虚拟环境，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身份使用virtual_env进行编译

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

我以root身份运行：

make install

我设置了WSGIPythonHome&路径在http.conf

  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

当我运行Hello World应用程序时， strong> work

  def application（environ，start_response）：
 status ='200 OK'
 output ='Hello World！'
 response_headers = [（'Content-type'，'text / plain'），
（'Content-Length'，str（len（输出））） ] 
 start_response（status，response_headers）
 
 return [output] 
  

当我尝试导入模块时，失败：

  import sys;引发异常（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] [通知] Apache / 2.2.20（Ubuntu）mod_wsgi / 3.3 Python / 2.6.7配置 - 恢复正常操作

'/usr/lib/python2.6/lib-tk'，
'/ home / andy /dev/python/async-mongo/lib/python2.6/site-packages']

我猜想某处某处我仍然引用旧的系统级python，但我不明白在哪里。如何解决这个问题？

解决方案

你在这里提出例外：

  import sys;提高异常（sys.path）
  

I'm setting up Django with apache, mod_wsgi, virtual env

I have a virtual env that I want to use here: [Missleading name - long story!] /home/andy/Dev/python/async-mongo/

I downloaded mod_wsgi and compiled it with virtual_env as root

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

I ran as root:

make install

I setup WSGIPythonHome & Path in http.conf

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

I think I followed the instructions at http://code.google.com/p/modwsgi/wiki/VirtualEnvironments

When I run the 'Hello World' app it works

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]

When I try to import a module it fails:

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]

The error I see in the apache logs is:

[Fri Mar 30 15:09:53 2012] [notice] Apache/2.2.20 (Ubuntu) mod_wsgi/3.3 Python/2.6.7 configured -- resuming normal operations

........

Exception: ['/home/andy/dev/python/async-mongo', '/home/andy/dev/python/async-mongo/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg', '/home/andy/dev/python/async-mongo/lib/python2.6/site-packages/pip-1.0.2-py2.6.egg', '/home/andy/dev/python/async-mongo/lib/python2.6/site-packages/txmongo-0.3-py2.6-linux-i686.egg', '/home/andy/dev/python/async-mongo/lib/python2.6', '/home/andy/dev/python/async-mongo/lib/python2.6/plat-linux2', '/home/andy/dev/python/async-mongo/lib/python2.6/lib-tk', '/home/andy/dev/python/async-mongo/lib/python2.6/lib-old', '/home/andy/dev/python/async-mongo/lib/python2.6/lib-dynload', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/home/andy/dev/python/async-mongo/lib/python2.6/site-packages']

I am guessing that somewhere somehow I am still referencing the old system level python but I can not understand where. How can I fix this?

解决方案

You are raising an exception here:

import sys; raise Exception(sys.path)
