Python Buildpack Install Steps
TODO: Add context on Python install steps, such as why symlinking vs copying
Installing Python packages using Pip
Convention: Use python process to invoke Pip
We don't use this convention (yet) but this is an upcoming change being considered.
This is a bigger concern on Windows than it is in Linux environments, but an emerging convention in the Python community is to invoke pip using:
python3 -m pip [options]
Invoking pip this way ensures correct location - python knows where these packages are stored because it put them there (defaults to Python's pathing info).
All normal command line options are available using this method.
