我无法让wsgi为我的项目'mofin'导入我的设置文件 .

apache错误日志中的错误列表如下所示

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.load_middleware()
  File "/usr/lib/python2.5/site-packages/django/core/handlers/base.py", line 31, in load_middleware
    for middleware_path in settings.MIDDLEWARE_CLASSES:
  File "/usr/lib/python2.5/site-packages/django/conf/__init__.py", line 28, in __getattr__
    self._import_settings()
  File "/usr/lib/python2.5/site-packages/django/conf/__init__.py", line 59, in _import_settings
    self._target = Settings(settings_module)
  File "/usr/lib/python2.5/site-packages/django/conf/__init__.py", line 94, in __init__
    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

我在这里列出的"hello world!" wsgi应用程序(http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide)工作正常 .

使用python manage.py(runserver | shell | syncdb |测试存储),settings.py文件可以正常加载 .

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-dadload','/ usr / lib / python2.5 / site-package','/ 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shell,那么sys.path就是

['/ 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-dadload','/ usr / lib / python2.5 / site-package','/ usr /lib/python2.5/site-packages/gtk-2.0' ]

    如果您有一个与项目名称相同的应用程序(项目的子目录,其中包含一个init文件),也会发生这种情况 . 您的settings.py文件可能位于项目文件夹中,但似乎django系统的一部分首先查找项目内部的模块,其名称与项目相同,并且当它在那里找不到settings.py时,它失败了一个误导性的消息 .

    -uniquename1
    
    ---settings.py
    
    ---manage.py
    
    ---application1
    
    -----file.py
    
    -----file2.py
    
    ---uniquename1  (problem, rename this to some other unique name)
    
    -----file.py
    
    -----file2.py
    

    还有别的东西可以检查其他有这个问题的人 . 适用于Django 1.3以及其他可能的应用程序 .

    我有一个类似的权限问题,虽然我的settings.py具有正确的权限,但.pyc没有!所以要注意这一点 .

    我找到了答案......文件权限 . / home / django设置为700.即只有django可以查看内容 . apache作为Apache运行,因此无法通过/ home / django .

    我认为在加载django之前,你需要在apache中的wsgi脚本中使用前导斜杠 .

    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()
    

    在我的情况下

    import os
    import sys
    if os.uname()[1] == 'vivien':
        sys.path.append('/home/www/sitebuilder.blacknight.ie/web/')
        os.environ['DJANGO_SETTINGS_MODULE'] = 'gibo.dev_settings'
    elif os.uname()[1] == 'thingy':
        sys.path.append('/home/www/sitebuilder.blacknight.ie/web/')
        os.environ['DJANGO_SETTINGS_MODULE'] = 'gibo.dev_settings'
    else:
        sys.path.append('/home/www/sitebuilder.blacknight.ie/web/')
        os.environ['DJANGO_SETTINGS_MODULE'] = 'gibo.settings'
    
    import django.core.handlers.wsgi
    application = django.core.handlers.wsgi.WSGIHandler()

    此问题的另一个原因是您不能将您的应用程序命名为另一个python模块 . 例如,我打电话给我的 site ,很少意识到 site 已经是一个python模块 .

    您可以通过启动python并运行 import sitehelp(site) 来检查这一点,它会显示它没有使用您的模块 . 这当然会在django尝试导入不存在的 site.settings 时给出错误 .

    可能的问题:

    你忘记了__init__.py文件,它必须在你的项目中以及你认为用于导入的python模块的所有目录中 .

    您可以尝试的其他方法是将路径直接添加到manage.py文件中,例如:

    import sys
    
    ...
    ...
    
    sys.path.insert(0, '/home/django/mofin/trunk')
    

    我希望它有所帮助

    我有同样的问题,但另一种解决方案:

    我的项目文件夹完全被命名为我的应用程序之一 .

    我有:

    /家/对myApp
    /home/myApp/settings.py
    /home/myApp/manage.py
    /home/myApp/rights.py
    /家庭/对myApp /静态/
    /家庭/对myApp /静态/
    / home / myApp / myApp /model.py
    / home / myApp / myApp /admin.py
    / home / myApp / myApp /viewss.py.

    这种树似乎不太容易 . 我更改了项目根文件夹的名称,问题解决了!

    (我为Django deployment problem in Apache/mod_wsgi. ImportError: Could not import settings 'site.settings'写了同样的答案,以防有人发现这个问题 . )

    在您的情况下,这似乎不是问题,但是当我使用WSGIPythonPath指令(而不是.wsgi文件)来设置 sys.path 时,我运行了相同的ImportError . 这工作正常,直到我切换到以守护进程模式运行WSGI . 一旦你这样做,你必须使用WSGIDaemonProcess指令的 python-path 参数 .

    在我的情况下,我有 circular import 导致此错误 . 从 settings.py 我在另一个模块中导入一个函数,并从该模块导入一个设置变量 . 要修复它,而不是直接从设置导入,我这样做:

    from django.conf import settings

    让我补充一下我对这个问题的经验 . 在头部敲打几个小时并从上面的答案中尝试所有后,我发现settings.py文件中的几行会导致问题:

    from south.modelsinspector import add_introspection_rules
    add_introspection_rules([], ["^dynamicsites.fields.FolderNameField"])
    add_introspection_rules([], ["^dynamicsites.fields.SubdomainListField"])
    

    之后我制作了settings.py的副本,命名为scripts_settings.py,然后使用该文件,现在一切正常 .

    初看起来我会说python路径是错误的,但与交互式shell相比它看起来还不错 . 所以也许试试这个:

    from django.core.management import setup_environ
    from mofin import settings
    
    setup_environ(settings)

    我打算说你可以在你的wsgi文件中插入/附加你的项目目录到你的sys.path但是你的设置文件是

    /home/django/mofin/trunk/mofin/settings.py
    

    那你应该在那里好 .

    Is it on sys.path? Does it have syntax errors?
    

    那几乎总结了你在寻找什么 .

    有趣的是错误传播:

    for middleware_path in settings.MIDDLEWARE_CLASSES:
    

    但你有似乎是exact default .

    您可能想要检查wsgi指向哪个python解释器 . 你打算使用virtualenv但是wsgi正在考虑你的系统安装吗?

    您还可以设置运行wsgi的用户和组 . 我使用类似的东西:

    WSGIDaemonProcess mysite.com user = skyl group = skyl processes = n threads = N python-path = / home / skyl / pinax / pinax-env2 / lib / python2.6 / site-packages

    再添加两行代码

    sys.path.append('/home/django/mofin/mofin')
    sys.path.append('/home/django/mofin/trunk/mofin/mofin')
    

    到你的wsgi文件下面的行:

    sys.path.append('/home/django/mofin/trunk/mofin/')

    我遇到了类似的问题,在我的python中使用以下片段解决了这个问题:

    ALLDIRS = ['/var/www/MarkerDB/']
    
    import sys 
    import site 
    
    # Remember original sys.path.
    prev_sys_path = list(sys.path) 
    
    # Add each new site-packages directory.
    for directory in ALLDIRS:
      site.addsitedir(directory)
    
    # Reorder sys.path so new directories at the front.
    new_sys_path = [] 
    for item in list(sys.path): 
        if item not in prev_sys_path: 
            new_sys_path.append(item) 
            sys.path.remove(item) 
    sys.path[:0] = new_sys_pat

    我刚刚遇到此错误,解决方案是通过myvenv / source / activate启用我的虚拟环境 .
