How to fix error "ERROR: Command errored out with exit status 1: python." when trying to install django-heroku using pip [duplicate]

Question

I am trying to install django-heroku using pip, but it keeps running into an error.

I have seen suggestions telling me to make sure my Python version in Heroku is up to date. I have already done that. After pushing to Heroku master, I ran the install command, but it gives me the following errors.

pip install django-heroku 

Error:

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found
