Apache2&Django - NameError：未定义名称"AttributeError"

Question

我遵循了几乎所有的官方文档，让我的Django项目在我的Ubuntu 18.04 v-server上运行。它似乎奏效了。。。sudo服务apache2状态->一切都很好。

我第一次注意到，当我的模板在没有服务器重启的情况下无法更新时，就会出现问题，这不是Django的常见行为(即使在生产环境中也是如此(。每当我重新启动服务器时，我都会在apache2/error.log中收到这个错误。虽然服务器一直在工作，但我想弄清真相。

• Ubuntu 18.04
• Python3.8.0，并通过更新备选方案链接到python命令
• Python在venv中运行

项目结构：

in /var/www/:
|-- my_app
|   |-- my_app
|   |   |-- __init__.py
|   |   |-- asgi.py
|   |   |-- settings.py
|   |   |-- urls.py
|   |   `-- wsgi.py
|   |-- db.sqlite3
|   |-- manage.py
|   |-- media
|   |-- .my_app (python venv)
|   |-- my_subapp
|   |   |-- __init__.py
|   |   |-- admin.py
|   |   |-- apps.py
|   |   |-- migrations
|   |   |-- models.py
|   |   |-- tests.py
|   |   |-- urls.py
|   |   `-- views.py
|   `-- templates
|       |-- base.html
|       `-- index.html

当它似乎是一个开箱即用的标准python类时，有什么可能出错的建议吗？为什么它会说"AttributeError not found？"。。。感谢您的帮助：-(

我花了一天时间才发现问题所在-感谢mod_wsgi的创建者Graham Dumpleton解释了一切。你可以在这里查找：
