让 Python 2.6 看到 Django
为了让 mod_wsgi 在 CentOS 5.4 上运行，我做了一次痛苦的尝试，按照 此处说明。配置看起来很好，除了当尝试 ping 服务器时，Apache 日志打印此错误：
mod_wsgi (pid=20033, process='otalo', application='127.0.0.1|'): Loading WSGI script '...django.wsgi'.
[Sat Mar 27 16:11:45 2010] [error] [client 171.66.52.218] mod_wsgi (pid=20033): Target WSGI script '...django.wsgi' cannot be loaded as Python module.

[Sat Mar 27 16:11:45 2010] [error] [client 171.66.52.218] ImportError: No module named django.core.handlers.wsgi
当我转到 python2.6 安装的命令行并尝试“导入 Django”时，找不到模块（导入错误）。但是，我的默认 Python 2.4 安装（仍然工作正常）能够成功导入。如何将 Python 2.6 指向 Django？
In a harrowing attempt to get mod_wsgi to run on CentOS 5.4, I've added Python 2.6 as an optional library following the instructions here. The configuration seems fine except that when trying to ping the server the Apache log prints this error:
mod_wsgi (pid=20033, process='otalo', application='127.0.0.1|'): Loading WSGI script '...django.wsgi'.
[Sat Mar 27 16:11:45 2010] [error] [client 171.66.52.218] mod_wsgi (pid=20033): Target WSGI script '...django.wsgi' cannot be loaded as Python module.

when I go to my python2.6 install's command line and try 'import Django', the module is not found (ImportError). However, my default Python 2.4 installation (still working fine) is able to import successfully. How do I point Python 2.6 to Django?

您需要专门安装 Django 以及要使用它的 Python 版本 - 2.4 和 2.6 的安装始终是分开的（它们必须是 - 二进制和字节码格式不兼容！）。我不知道 CentOS 为此提供了哪些可能性（如果有的话）——我会得到 Django 的源 并从源安装（归结为：下载、tar、cd，最后是一个简单的
sudo python2.6 setup.py install——或者以其他方式运行 Python 2.6 安装） 。作为一名比系统管理员更好的开发人员，我总是倾向于从源代码安装真正处于我正在做的事情核心的东西（尤其是 Python 版本和扩展）。You need to install Django specifically with/for the Python version that's meant to use it -- installs for 2.4 and 2.6 are always going to be separate (they have to be -- there are incompatibilities in binary and bytecode formats!). I don't know what, if any, possibilities CentOS offers for that -- I'd get Django's sources and install from sources (which boils down to: download, tar, cd, and finally a simple
sudo python2.6 setup.py install-- or however else you run your 2.6 install of Python). Being a much better developer than I'm a system administrator, I always have a bias in favor of installing from sources for stuff that's really at the core of what I'm doing (especially Python versions and extensions).我创建了一篇文章 链接文本我在 Redhat 和 CentOS 上使用 Django 的经历。我升级了我正在使用的 python 版本并从 init.d 脚本开始。
I created a write up link text of my experiences of getting Django working on Redhat and and CentOS. I upgraded the version of python that I was using and started with init.d scripts.
