Answer 1

After installing gunicorn use below command

whereis gunicorn

It will give exact path where gunicorn located, then use that path in your gunicorn conf file. Happy coding!!

Answer 2

I think that the issue is with the third line of your configuration file. The error message indicates that the gunicorn executable is not available in the /home/ubuntu/myvenv/js/bin directory. If you do ls /home/ubuntu/myvenv/js/bin/gunicorn you probably will get an error message.

I think you would need to check if you have correctly installed gunicorn in your virtual environment, using eg pip install gunicorn . Have a look at this article ; I think it would be helpful.
