异常值:'NoneType'对象没有属性'endswith'

是的,我正在尝试根据当前的实时网站设置django开发网站。我已经设置了新的virtualenv并安装了所有的依赖项。我还制作了数据库的副本并完成了一个新的数据库转储。我现在得到上面的错误,我不明白为什么。

我的django.wsgi文件似乎指向了virtalenv。这是关于错误的更多信息。

我希望这已经足够了,但我真的不知道为什么会这样!

2 个答案:

答案 0 :(得分:3)

在本节中:

# URL that handles pages media and uses <MEDIA_ROOT>/pages by default.
_media_url = getattr(settings, "STATIC_URL", settings.MEDIA_URL)
PAGES_MEDIA_URL = getattr(settings, 'PAGES_MEDIA_URL',
    join(_media_url, 'pages/'))

STATIC_URL不在设置中,settings.MEDIA_URLNone。您似乎需要修改设置。

答案 1 :(得分:1)

在这一行,

ile "/usr/lib/python2.6/posixpath.py" in join
  67.         elif path == '' or path.endswith('/'):

路径为无。所以非类型(“路径”)必须属性.endswith

我建议像其他用户说的那样把完整的追溯错误并检查你的代码,看看为什么路径是无。
