Heroku Deployment - PermissionError: [Errno 13] Permission denied: '/etc/passwd-'

Can anyone help me with this error? I don't what's wrong with the code. is it a database credentials error? Is it an application code error? Is it a Linux/Unix related error?

This is my first time to deploy my application on Heroku but I got this error message:

PermissionError: [Errno 13] Permission denied: '/etc/passwd-'

   python ph_dorms/manage.py collectstatic --noinput

   !     Error while running '$ python ph_dorms/manage.py collectstatic --noinput'.
   See traceback above for details.
   You may need to update application code to resolve this error.
   Or, you can disable collectstatic for this application:
      $ heroku config:set DISABLE_COLLECTSTATIC=1
   https://devcenter.heroku.com/articles/django-assets
  !     Push rejected, failed to compile Python app.
  !     Push failed
Solution

  • The complicated part in deploying a django webapp is most of the time related to the collectstatics only if you didn't setup everything correctly to serve static files from the same server.

    First disable the collectstatics running the following in your terminal or cmd:

    heroku config:set DISABLE_COLLECTSTATIC=1

    Then deploy again.
