Apache server is not starting

I have one python Django project on our intranet server folder like "//xxx.com/.../myproject/", and I set up virtual env under it as python interpreter "//xxx.com/.../myproject/py37-venv".

I installed WampServer on my desktop computer (windows 10) and also on one windows server 2016, and testing apache server for Django server deployment.

I followed this article to test apache: https://www.codementor.io/@aswinmurugesh/deploying-a-django-application-in-windows-with-apache-and-mod_wsgi-uhl2xq09e

1. Added the following into httpd.conf:

   LoadFile "C:/Python/Python37_64//python37.dll"
   
   LoadModule wsgi_module "//xxx.com/.../myproject/py37-venv/lib/site-packages/mod_wsgi/server/mod_wsgi.cp37-win_amd64.pyd"
   
   WSGIPythonHome "//xxx.com/.../myproject/py37-venv"
   

2. Replace all 80 ports in httpd.conf to 8888.

3. I tested with httpd.exe -t, reported "Syntax ok"

4. I tested with httpd.exe -e debug, it stopped and exit after this as below. I guess it is supposed to be continuously running after "generating secret...", right? It seems crashed although the modules loaded successfully:

5. I tried: httpd.exe -k start -n "Apache", returned nothing.

6. I tried to start it on the services panel, but it told me that it cannot be started on a local computer.

Does it seem something is wrong, Any ideas?
