【问题描述】：

我正在使用

% url facebook_xd_receiver % 

在我的一个 html 文件中。当我使用命令运行我的项目时，这工作得很好

python manage.py runserver

但是同一个项目停止运行并在该行给我一个“TemplateSyntaxError” % url facebook_xd_receiver %

谁能告诉我通过命令行运行的开发服务器和apache服务器之间可能有什么区别。

在配置 Apache 服务器时我有什么遗漏吗？还是 Django 的问题？

Exception Type: TemplateSyntaxError at /djangonyc/exampleapp/
Exception Value: Caught an exception while rendering: No module named app.models

【问题讨论】：

没有看到实际的错误报告。

尤其是 url 问题通常给出“NoReverseMatch”而不是“TemplateSyntaxError”。

【参考方案1】：

实际的错误信息是这样的：

Caught an exception while rendering: No module named app.models

因此，您尝试在代码中的某处导入app.models，它要么不存在，要么不在您的pythonpath 中。在 url 反转期间发生这种情况的原因是，为了找到所有可能的 URL，Django 导入所有视图 - 显然其中一个有错误。
