[Django]-Why gunicorn command not found with gunicorn installed?

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
Author-email: benoitc@e-engura.com
License: MIT
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)

I had the same problem on Debian.

It turns out that on Debian the documentation advises to install gunicorn via apt:

$ sudo apt install gunicorn

Installing gunicorn from source saved me after 2 hours trying!

pip3 install git+https://github.com/benoitc/gunicorn.git

i just created a file named gunicorn and type these codes below which is the same as my development server , and included it into system path,such as /usr/bin

#!/usr/local/bin/python3.4

#-*- coding: utf-8 -*-
import re
import sys

from gunicorn.app.wsgiapp import run


if __name__ == '__main__':
        sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$','',sys.argv[0])
        sys.exit(run())

in this way, it solved my problem,but still confused me,why gunicorn command not generated and included into system path automatically?and why my development server did ,both the same OS (centos 6.5 x64)

If you installed python3 from source compiled, you should export your python3 PATH:

export PATH=$PATH:/usr/local/python3/bin

Are you use python3.4-venv?

if true

• Delete env folder
• Just reinstall: python3.4-venv. Ex for ubuntu:
  apt install python3.4-venv
• Exec: python3.4 -m venv env
• source env/bin/activate
• reinstall gunicorn by : pip3 install gunicorn or install from requirements.txt by pip3 install -r requirements.txt

go to terminal and change directory to environment and then type the below command.

pip install gunicorn
