apache2和mod wsgi：目标WSGI脚本不能作为Python模块加载

我想在apache2上安装mod_wsgi，在Ubuntu上。所以我安装了libapache2-mod-wsgi包，我用a2enmod激活了他。apache2和mod wsgi：目标WSGI脚本不能作为Python模块加载

我有一个网站（languageAnalyz），我正在尝试使用mod_wsgi。当我打电话本地主机/ languageAnalyz，我得到一个错误500

在Apache2的日志，我可以看到这一点：

[Sun Aug 25 11:28:21 2013] [error] [client 127.0.0.1] mod_wsgi (pid=4993): Target WSGI script '/var/www/languageAnalyz/test-wsgi.py' cannot be loaded as Python module.

我GOOGLE了这个错误，我发现很多解决方案（大多数时候为Django项目）。我无意中发现，我需要创建一个__init__.py文件。我做了什么，这是我__init__.py文件：

__all__ = ['app','get_size_dir','get_nbrf_dir','getStats'] #name of my functions 
import index # my three python files 
import analyz 
import test-wsgi

在__all__名单，这是在这三个文件的功能名称。我只是尝试启动test-wsgi.py，并得到了同样的错误500

这里是我的test-wsgi.py文件：

import os,sys 
sys.path.append(os.path.dirname(__file__)) 
from cgi import escape,parse_qs 
from flup.server.fcgi import WSGIServer 
def app(environ, start_response): 
    start_response('200 OK',[('Content-Type','text/plain; charset=utf-8')]) 
    yield "hello world!" 
WSGIServer(app).run()

那么，什么是错的？谢谢

编辑：这里是我的Apache2的conf：

WSGIPythonPath /var/www/languageAnalyz 
<VirtualHost *:80> 
    ... 
    <Directory /var/www/languageAnalyz/> 
    Options +Indexes ExecCGI FollowSymLinks MultiViews 
    AllowOverride None 
    Order allow,deny 
    Allow from all 
    DirectoryIndex index.py 
    SetHandler wsgi-script 
    </Directory> 
    ... 
</VirtualHost>

Edit_bis：所以我尝试这样做，因为我的Django的文档阅读。我改变我的Apache2的conf到：

WSGIPythonPath /var/www/languageAnalyz 
<VirtualHost *:80> 
    ... 
    WSGIScriptAlias /IPA /var/www/languageAnalyz/testwsgi.py 
    <Directory /var/www/languageAnalyz/> 
      Options +Indexes FollowSymLinks MultiViews 
      AllowOverride None 
      Order allow,deny 
      Allow from all 
      DirectoryIndex testwsgi.py 
    </Directory> 

    ... 
</VirtualHost>

我重新启动的Apache2，我得到了同样的错误，还有一个前：

Edit_ter：

好吧，我刚刚成功发射testwsgi.py。我改变我的应用程序功能到应用程序，并在结尾添加一些行：

if __name__ == '__main__': 
    from wsgiref.simple_server import make_server 
    server = make_server('localhost', 8080, application) 
    server.serve_forever()

事件我不知道，为什么它的工作，为什么它不工作之前。 ......现在，我得到了一些问题，打开文件，与他们的路径（配置文件或模板文件...）

我尝试用绝对路径，它没有工作太...

您可能也想看看这些问题：http://stackoverflow.com/questions/17766595/403-forbidden-error-with-django-and-mod- wsgi/28394998＃28394998和http://stackoverflow.com/questions/3749331/django-with-mod-wsgi-returns-403-error – jknappen

你似乎会跟着错误的文档为初学者。对于mod_wsgi的使用：

https://docs.djangoproject.com/en/dev/howto/deployment/wsgi/modwsgi/

你似乎是使用文档FASTCGI部署。

而且，你不能做：

import test-wsgi

一个Python模块名称不能以 ' - ' 它。

总之，重新阅读（或阅读）有关部署的Django文档。

我甚至比以前有更多的错误。我得到了同样的错误，并在此之前有另一个错误。我编辑我的帖子。 – vekah

好吧，我刚刚成功启动了testwsgi.py。我将我的应用程序函数改为应用程序，并在末尾添加一些行：'if __name__ =='__main__'： from wsgiref.simple_server import make_server server = make_server（'localhost'，8080，application） server。 serve_forever（）' 我事件不知道，为什么它的工作，为什么它不工作之前。 ... 现在我得到了一些问题打开文件，其路径（配置文件，或模板文件...） – vekah

你不能使用相对路径名，你必须使用绝对路径名。当前的工作目录不会在你期望的位置。请参阅http://code.google.com/p/modwsgi/wiki/ApplicationIssues#Application_Working_Directory –

对于不同的文件我有同样的问题，并使文件世界可执行文件修复它为我。你当然会希望将其锁定到所需的用户，你已经缩小下来作为您的问题后：

chmod a+x test-wsgi.py

对我来说，问题是WSGI Python版本不匹配。我使用python 3，因此：

$ sudo apt-get remove libapache2-mod-python libapache2-mod-wsgi 
$ sudo apt-get install libapache2-mod-wsgi-py3
