python - wsgi.py 在 apache 上的 virtualenv 中失败，并显示“没有名为 'django' 的模块”

Question

我在 Amazon Linux EC2 服务器上运行 Django webapp，并且已正确安装和验证 Apache 和 mod_wsgi。我如下所示配置了 Apache 配置文件，并通过打印验证了 Python 中是否加载了正确的路径sys.path（显示在错误日志中），但是，我不断收到 500 错误，wsgi.py文件失败并出现ModuleNotFoundError: No module named 'django'错误。在 apache 配置文件中使用守护程序模式时出现相同的错误。我错过了什么？

我的 virtualenv 在/var/www/html/test，我的 webapp 在/var/www/html/ai_demo_webapp/webapp（这是我的manage.py文件的位置）。我正在使用 Apache 2.2.34 和 mod_wsgi 的 pip 版本，并将 wsgi 模块加载到 apache 配置文件中为LoadModule wsgi_module "/home/ec2-user/.local/lib/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so".

wsgi.py

import os
import sys

print(sys.path)

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "webapp.settings")

application = get_wsgi_application()

阿帕奇配置文件

WSGIPythonHome /var/www/html/test
WSGIPythonPath /var/www/html/ai_demo_webapp/webapp

<VirtualHost *:80>
WSGIScriptAlias / /var/www/html/ai_demo_webapp/webapp/webapp/wsgi.py

<Directory /var/www/html/ai_demo_webapp/webapp/webapp>
