500服务器错误目标WSGI脚本无法作为Python模块错误Django加载

Question

我正在尝试在VPS上部署一个网站。在这之前，我遇到了python版本的问题。问题是我不能安装最新的Django版本。我联系了技术支持，他们将python版本更新到了3.7。设置模块安装后，我使用venv在端口8000上进行了一些测试，应用程序正常运行。测试后，我设置了Apache2。现在显示500个内部服务器错误我认为这是python版本错误

如果你能帮助我，我将非常感激和高兴。请随时问我任何问题

操作系统：

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.7 LTS
Release:        16.04
Codename:       xenial

sudo chmod 775 exampleproject

sudo chown -R :www-data exampleproject/media/

已安装的模块

(venv) alpcusta@example:~$ pip freeze
asgiref==3.3.1
Django==3.1.3
django-cleanup==5.1.0
Pillow==8.0.1
pytz==2020.4
sqlparse==0.4.1

我确实尝试了以下步骤： 卸载django并重新安装

删除venv文件夹并卸载venv，然后使用requirement.txt文件安装venv

$ sudo apt-get remove python3-venv  
$ sudo apt-get install python3.7-venv
$ python3.7 -m venv venv
$ pip install -r requirements.txt

同样的错误还在重复
