apache2和mod wsgi：目標WSGI腳本不能作爲Python模塊加載

我想在apache2上安裝mod_wsgi，在Ubuntu上。所以我安裝了libapache2-mod-wsgi包，我用a2enmod激活了他。apache2和mod wsgi：目標WSGI腳本不能作爲Python模塊加載

我有一個網站（languageAnalyz），我正在嘗試使用mod_wsgi。當我打電話本地主機/ languageAnalyz，我得到一個錯誤500

在Apache2的日誌，我可以看到這一點：

[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.

[Sun Aug 25 11:28:21 2013] [error] [client 127.0.0.1] SystemExit: 0

我GOOGLE了這個錯誤，我發現很多解決方案（大多數時候爲Django項目）。我無意中發現，我需要創建一個__init__.py文件。我做了什麼，這是我__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__名單，這是在這三個文件的功能名稱。我只是嘗試啓動test-wsgi.py，並得到了同樣的錯誤500

這裏是我的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()

那麼，什麼是錯的？謝謝

編輯：這裏是我的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：所以我嘗試這樣做，因爲我的Django的文檔閱讀。我改變我的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>

我重新啓動的Apache2，我得到了同樣的錯誤，還有一個前：

Edit_ter：

好吧，我剛剛成功發射testwsgi.py。我改變我的應用程序功能到應用程序，並在結尾添加一些行：

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，爲什麼它的工作，爲什麼它不工作之前。 ......現在，我得到了一些問題，打開文件，與他們的路徑（配置文件或模板文件...）

您可能也想看看這些問題：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

你似乎會跟着錯誤的文檔爲初學者。對於mod_wsgi的使用：

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

你似乎是使用文檔FASTCGI部署。

而且，你不能做：

import test-wsgi

一個Python模塊名稱不能以 ' - ' 它。

總之，重新閱讀（或閱讀）有關部署的Django文檔。

我甚至比以前有更多的錯誤。我得到了同樣的錯誤，並在此之前有另一個錯誤。我編輯我的帖子。 – vekah

好吧，我剛剛成功啓動了testwsgi.py。我將我的應用程序函數改爲應用程序，並在末尾添加一些行：'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，爲什麼它的工作，爲什麼它不工作之前。 ... 現在我得到了一些問題打開文件，其路徑（配置文件，或模板文件...） – vekah

你不能使用相對路徑名，你必須使用絕對路徑名。當前的工作目錄不會在你期望的位置。請參閱http://code.google.com/p/modwsgi/wiki/ApplicationIssues#Application_Working_Directory –

對於不同的文件我有同樣的問題，並使文件世界可執行文件修復它爲我。你當然會希望將其鎖定到所需的用戶，你已經縮小下來作爲您的問題後：

chmod a+x test-wsgi.py

對我來說，問題是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
