Problema com instalação do django-heroku

Durante a instalação apareceu esse erro e me travou no curso :(

    It appears you are missing some prerequisite to build the package from source.

    You may install a binary package by installing 'psycopg2-binary' from PyPI.
    If you want to install psycopg2 from source, please install the packages
    required for the build and try again.

    For further information please check the 'doc/src/install.rst' file (also at
    <https://www.psycopg.org/docs/install.html>).

Olá,

seu sistema não esta conseguindo compilar a lib. Pelo menos é isso que o erro está logando.

A psycopg2-binary resolve isso. Altere no seu requirements para psycopg2-binary.

Apesar de existir outras possiveis soluções, eu nunca utilizo a django-heroku. Ela não é essencial para deploy no Heroku.

Caso opte por não utilizá-la, o que recomendo, é só não add as configs no settings.py.
