的Apache2和MOD WSGI：目标WSGI脚本无法加载Python模块 [英] apache2 and mod wsgi : Target WSGI script cannot be loaded as Python module
问题描述
我想上的Apache2安装mod_wsgi的，在Ubuntu。
所以，我的libapache2安装-MOD-WSGI包，我激活了他a2enmod。
I am trying to install mod_wsgi on apache2, on ubuntu. So I install libapache2-mod-wsgi package, I activate him with a2enmod.
我有一个网站（languageAnalyz），我试图用mod_wsgi的使用。
当我打电话本地主机/ languageAnalyz，我得到一个错误500。
I got a web site (languageAnalyz), that I am trying to use with mod_wsgi. When I call localhost/languageAnalyz, I got an error 500.
在日志中的Apache2，我可以看到这一点：
In apache2 log, I can see this :

我GOOGLE了这个错误，我觉得很多解决方案（大多数时候为Django项目）。
我undsertand，就是我需要创建一个 __ __初始化。PY 文件。
我做了什么，这是我的 __ __初始化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 __ __所有名单，这是在这三个文件的函数的名称。
我只是尝试启动test-wsgi.py，并得到了同样的错误500。
In the __all__ list, this is the name of the functions in the three files.
I am just trying to launch test-wsgi.py, and get the same error 500.
下面是我的test-wsgi.py文件：
Here is my test-wsgi.py file :
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
So what's wrong ? Thank you,
编辑：
这里是我的Apache2 CONF：
Edit : here is my apache2 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：
于是，我试着做我的Django的文档阅读。
我改变我的Apache2的conf为：
Edit_bis : So I try to do as I read on django doc. I change my apache2 conf to :
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，在此之前多了一个：
I restart apache2, and I got the same error, and one more before :

Edit_ter :
好吧，我刚刚成功发射testwsgi.py。我改变我的应用程序功能分为应用程序，并在结尾添加一些行：
Ok, I just successfully launch testwsgi.py. I change my app function into application, and I add some lines at the end :
if __name__ == '__main__':
from wsgiref.simple_server import make_server
server = make_server('localhost', 8080, application)
server.serve_forever()
我的事件不知道，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，用自己的路径（配置文件或模板文件...）
I event don't know, why it's working, why it was not working before. ... And now I got some problem to open files, with their path (config files, or templates files ...)

[Sun Aug 25 13:10:51 2013] [error] [client 127.0.0.1] flangs=open('config/languages.yml')
我尝试用绝对路径，它没有工作过...
I try with absolute path, it didn't work too ...
推荐答案
有关我的问题是WSGI Python版本不匹配。我使用python 3，因此：
For me the problem was wsgi python version mismatch. I was using python 3, so:
$ sudo apt-get remove libapache2-mod-python libapache2-mod-wsgi
$ sudo apt-get install libapache2-mod-wsgi-py3
