如何在使用Django与WSGI时停止出现ImportError: Could not import settings 'mofin.settings'?
我无法让wsgi导入我项目'mofin'的设置文件。
来自apache错误日志的错误列表如下:
mod_wsgi (pid=4001): Exception occurred within WSGI script '/var/www/wsgi-scripts/django.wsgi'.
Traceback (most recent call last):
File "/usr/lib/python2.5/site-packages/django/core/handlers/wsgi.py", line 228, in __call__

self._target = Settings(settings_module)

raise ImportError, "Could not import settings '%s' (Is it on sys.path? Does it have syntax errors?): %s" % (self.SETTINGS_MODULE, e)
ImportError: Could not import settings 'mofin.settings' (Is it on sys.path? Does it have syntax errors?): No module named mofin.settings
我在这里找到的“hello world!” wsgi应用程序(http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide)运行得很好。
使用python manage.py(runserver|shell|syncdb|test store)时,settings.py文件加载正常,应用程序也能正常运行。
这是我的wsgi文件:
import os
import sys
sys.path.append('/home/django/mofin/trunk')
sys.path.append('/home/django/mofin/trunk/mofin')
print >> sys.stderr, sys.path
os.environ['DJANGO_SETTINGS_MODULE'] = 'mofin.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
错误日志中打印的sys.path是:
['/usr/lib/python25.zip', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/gtk-2.0', '/home/django/mofin/trunk', '/home/django/mofin/trunk/mofin']
如果我用manage.py打开一个交互式命令行,sys.path是:
['/home/django/mofin/trunk/mofin', '/usr/lib/python25.zip', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/gtk-2.0']

嘿,我想再补充一个关于这个问题的回答。我遇到的情况和这个一模一样,但问题不是文件权限。我当时在添加“项目的路径”,但没有同时添加“路径的上一级”。这里有一个链接,是 mod_wsgi 和 Django 整合的说明,帮我找到了答案。
我之前也遇到过类似的权限问题,虽然我的settings.py文件设置得没问题,但.pyc文件的权限却不对!!!所以要注意这一点。
如果你的应用程序(项目中的一个子目录,里面有一个初始化文件)和项目的名字是一样的,也可能会出现这个问题。你的settings.py文件可能在项目文件夹里,但看起来Django系统的一部分会首先在项目内部寻找一个和项目同名的模块,如果找不到settings.py,就会出现一个让人误解的错误信息。
-uniquename1
---settings.py
---manage.py
---application1
-----file.py
-----file2.py
---uniquename1 (problem, rename this to some other unique name)
-----file.py
-----file2.py
这只是给遇到这个问题的其他人提供的一个检查点。适用于Django 1.3,可能也适用于其他版本。
