为什么我的虚拟环境没有被 uwsgi 激活？

为什么我的虚拟环境没有被 uwsgi 激活？

在全新安装的 Debian Bullseye 上，我无法使用该uwsgi命令。它无法加载请求的虚拟环境。

这是失败的命令：

uwsgi --plugins http,python3 --wsgi-file wsgi.py --http :9090 --virtualenv /opt/example/virtualenv

的内容wsgi.py只是Django默认生成的文件，并添加了一条print()语句：

import os, sys
print(sys.path)
from django.core.wsgi import get_wsgi_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'example.settings')
application = get_wsgi_application()

这是该命令的输出uwsgi：

$ uwsgi --plugins http,python3 --wsgi-file wsgi.py --http :9090 --virtualenv /opt/example/virtualenv

如您所见，uwsgi通知我已检测到虚拟环境并具有“ Set PythonHome to /opt/example/virtualenv”，但语句的输出print()显示事实并非如此。

如果我手动激活虚拟环境，我可以确认 Django 已正确安装在虚拟环境中：

$ . /opt/example/virtualenv/bin/activate
$ python
Python 3.8.6 (default, Sep 25 2020, 09:36:53) 
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django.__file__
'/opt/example/virtualenv/lib/python3.8/site-packages/django/__init__.py'
>>>

出了什么问题？我该如何修复它？

我以前见过类似的东西，我所做的是uwsgi通过安装pip，所以当你运行它时，uwsgi已经“在”虚拟环境因此被激活。
