在Django中使用mod_python运行应用程序时出错

Question

我在使用win32系统，安装了python2.5、django1.2、apache2.2，还有mod_python3.3.1。

我已经正确安装了mod_python。我的应用程序名称是myapp.setting，路径是c:\myapp.setting。在myapp.settings文件夹里，有我的url.py、settings.py等文件。

现在在apache的httpd.conf配置文件中，我做了以下更改：

<Location "/mysite">
    SetHandler python-program
    PythonHandler django.core.handlers.modpython
    SetEnv DJANGO_SETTINGS_MODULE myapp.settings
    PythonDebug On
    PythonPath "['/'] + sys.path"
</Location>

我尝试了很多关于PythonPath的修改。但是当我在浏览器里输入http://localhost/mysite时，出现了以下错误：

MOD_PYTHON错误

ImportError: Could not import settings 'myapp.settings' (Is it on sys.path? Does it have syntax errors?): No module named myapp.settings

请帮帮我，我对Django还很陌生……

正如rebus在评论中所说，把你的项目叫做'myapp.settings'是没有意义的。这既不是一个应用程序（应用程序是网站的一个组成部分），也不是一个设置文件。给它起个合适的名字吧——如果你实在想不出来，可以叫它'mysite'。

最后，你应该避免使用mod_python，改用mod_wsgi。
