我从 git 克隆 repo。我创建 venv：
python -m venv myenv
/myenv/scripts/activate.bat
pip install -r requirements.txt
pip install mod_wsgi-4.6.5+ap24vc14-cp36-cp36m-win_amd64.whl
如果我从 myvenv 运行：
python manage.py runserver
是工作！
如果我从 apache 运行，则会出现错误：

httpd.conf 下面：

我将 PYTHONHOME 和 PYTHONPATH 设置为“C:\Users\user\AppData\Local\Programs\Python\Python36;C:\Users\user\AppData\Local\Programs\Python\Python36\Scripts”
我看了很多问题，例如：Windows 10 上的致命 Python 错误 ModuleNotFoundError：没有名为“encodings”的模块但这个错误只出现在apache中。
问题是 Windows 上的 Apache 当作为Service 不接听PYTHONHOME环境变量使用正确的 Python 安装需要它。
如果没有找到它，它会给出一个非常误导性的错误encdongs module not found
Fatal Python error: initfsencoding: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'
要使其正常工作，请在 Windows 终端或 CMD 中将 Apache 作为标准可执行文件运行 -不作为服务:
set PYTHONHOME=<root-of-python-or-conda-env>
httpd // In this case, Apache server picks up PYTHONHOME and comes up
httpd -k start // as a service (need to be admin) - here it DOES NOT pick up PYTHONHOME and fails with the error above
另请注意，根据 mod_wsgi 作者的说法，在 Windows 上，Apache 似乎忽略了WSGIPython主页指令，所以不用费心去那个兔子洞。
