我正在尝试在我的 ubuntu 电脑上安装 django-cms。我收到此错误：

知道为什么会出现这个错误吗？

谢谢编辑-1—— 嗨，大家好，是的，你是对的，我没有将 cms_templates 放在 settings.py 中。我现在这样做了，但现在我收到了这个错误。

【问题讨论】：

【参考方案1】：

它正在寻找settings.CMS_TEMPLATES。它试图使 None 成为一个会引发该错误的元组。

确保您定义了CMS_TEMPLATES。

http://docs.django-cms.org/en/2.1.3/getting_started/tutorial.html#configuration-and-setup

【讨论】：

【参考方案2】：

您的 CMS_TEMPLATES 设置为无，我不知道那是什么，但我猜这是您需要在某处配置的设置。

【讨论】：

【参考方案3】：

settings.CMS_TEMPLATES 是None，我相信。如果没有相关代码示例，很难判断。
