python - Apache2&Django - NameError : name "AttributeError" is not defined

Question

我几乎按照所有官方文档来让我的 Django 项目在我的 Ubuntu 18.04 v-server 上运行。它似乎工作...... sudo service apache2 status -> 一切都很好。

[Sun May 03 16:07:20.489608 2020] [mpm_event:notice] [pid 11531:tid 139884218760128] AH00489: 
Apache/2.4.29 (Ubuntu) OpenSSL/1.1.1 mod_wsgi/4.7.1 Python/3.8 configured -- resuming normal operations

Command line: '/usr/sbin/apache2'

我首先注意到，如果我的模板在没有服务器重启的情况下不会更新，这不是 Django 的通常行为(即使在生产环境中)，某些东西会出现问题。每当我重新启动服务器时，我都会在 apache2/error.log 中收到此错误。尽管服务器继续工作，但我想深入了解这一点。

Ubuntu 18.04

Python3.8.0 并通过 update-alternatives

链接到 python-command

在 venv 中运行的 Python

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

有什么建议可能是错误的，为什么它说“找不到属性错误？”当它似乎是开箱即用的标准python类时...谢谢您的帮助:-)

我花了一天的时间才找出问题所在 - 感谢 Graham Dumpleton - mod_wsgi 的创建者解释了一切。你可以在这里查看:
