I faced the same issue and it turns out I had to add gunicorn binary path to Linux PATH variable. You can start by echoing $PATH to see all binary path listed on the system. Then find out where gunicorn is installed. For my case I was using python virtual environment and pyenv which helps manage several python versions and dependencies separately.

(venv3.6) dave@daverig (develop)✗ % pip show gunicorn
Name: gunicorn
Version: 19.7.1
Summary: WSGI HTTP Server for UNIX
Home-page: http://gunicorn.org
Author: Benoit Chesneau

Location: /home/dave/.pyenv/versions/3.6.2/envs/venv3.6/lib/python3.6/site-packages

Notice gunicorn is installed in /home/dave/.pyenv/versions/3.6.2/envs/venv3.6/lib/python3.6/site-packages and the corresponding path for the binaries for this particular python version is at /home/dave/.pyenv/versions/3.6.2/envs/venv3.6/bin. So I had to add that to Linux path via ~/.profile file like so;

export PATH=$PATH:$HOME/.pyenv/versions/3.6.2/envs/venv3.6/bin then ofcourse you want to refresh this using source ~/.profile or restart your terminal. Once I was able to do this, gunicorn binary was now available on my console;

(venv3.6) dave@daverig (develop)✗ % gunicorn --version
gunicorn (version 19.7.1)
