supervisor exiting with ENOENT

I am attempting to deploy a Django web application for the first time using NGINIX, Gunicorn and Supervisor on Digital Ocean Ubuntu 16.04 server. I am following the this linked tutorial.

I am having a trouble configuring Supervisor. When running this command...

sudo supervisorctl status automatedre

I get this error...

automatedre               FATAL     Exited too quickly (process log may have details)

The log file shows this...

supervisor: couldn't exec /home/automatedre/gunicorn_start: ENOENT
supervisor: child process was not spawned
supervisor: couldn't exec /home/automatedre/gunicorn_start: ENOENT
supervisor: child process was not spawned

[program:automatedre]
command=/home/automatedre/gunicorn_start
user=automatedre
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/home/automatedre/logs/gunicorn.log

I'm not sure where to go from here. I don't believe it is a file permission issue since I previously changed permission on gunicorn_start with this...

chmod u+x gunicorn_start

Any ideas on where I'm going wrong?

Solution

I previously left out the text below from the log file because I didn't think it was relevant...mistake.

/home/automatedre/gunicorn_start: 2: /home/automatedre/gunicorn_start: ^M: not found
/home/automatedre/gunicorn_start: 12: /home/automatedre/gunicorn_start: ^M: not found
/home/automatedre/gunicorn_start: 13: cd: can't cd to /home/automatedre/automatedre^M
/home/automatedre/gunicorn_start: 14: /home/automatedre/gunicorn_start: source: not found
/home/automatedre/gunicorn_start: 15: /home/automatedre/gunicorn_start: ^M: not found
/home/automatedre/gunicorn_start: 18: /home/automatedre/gunicorn_start: ^M: not found
/home/automatedre/gunicorn_start: 19: exec: ../venv/bin/gunicorn: not found

I initially created the /home/automatedre/gunicorn_start and /etc/supervisor/conf.d/automatedre.conf in my Brackets text editor on my windows machine which created this issue.

After doing some more digging, I learned that Windows/MS-DOS uses CR+LF to indicate end-of-lines and UNIX uses LF character to indicate line termination (EOL character).

This difference resulted in the ^M at the end of each line causing the file path not found error.

Recreating each file from the terminal with nano solved the issue.
