您好我正在尝试使用Ajax使用django-facebook connect为我的django应用程序实现facebook登录。我正在关注此链接以实现它facebook-django integration with ajax。在这样做时，我遇到了这个错误“TemplateSyntaxError at / registrationForm /
'facebookconnect'不是有效的标签库：找不到模板库facebookconnect，尝试过django.templatetags.facebookconnect，django.contrib.admin.templatetags.facebookconnect，facebookconnect.templatetags.facebookconnect“。我将把错误日志粘贴到这里环境：

答案 0 :(得分：1)
您的facebookConnect.py文件必须位于templatetags包裹内（必须有__init__.py才能将其作为包裹）。
在您的settings.INSTALLED_APPS设置中，您似乎还添加了facebookconnect，即使这不是应用（按目录结构进行）。相反，您应该将universityDB.universityDetails列为应用。
