Switches the last consumers of it to a simpler utility function that uses `pkgutil.find_loader()`: https://docs.python.org/3/library/pkgutil.html#pkgutil.find_loader Both of these consumers are covered by existing tests. Then removes `sp-grep` and the remaining parts of `pip-pop`. Closes @W-8208817@.
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.
