Deploy Python App To Heroku With Extra Pip Install

I'm trying to implement Deploy to Heroku functionality for my Python application: https://github.com/jet-admin/jet-bridge/tree/heroku It woks OK if just use requirements.txt to ins

Solution 1:

The Heroku Python buildpack has a hook where you can execute extra commands after the initial slug compilation.

To use it, you can add a bin/post_compile file, putting inside the shell commands for installing the extra packages.

You can even make it depend on an environment variable, like:

# assuming you have files mysql-requirements.txt and postgres-requirements.txtif [ "$JET_BRIDGE_DB" == "mysql" ]; thenecho"Installing Python dependencies for MySQL support"
    pip install -r mysql-requirements.txt
elseecho"Assuming Postgres database, installing Python dependencies"
    pip install -r postgres-requirements.txt
fi
