For some reason, RubyGems keeps installing gems in the directory of the old Scoop Ruby installation that I've wiped. Can I change the directory? I'm trying to find all my options before going straight to WSL. Thank you.

The location of installed gems is determined by two things:
What is compiled into the Ruby executable.
On
gem envthis isINSTALLATION DIRECTORY, unless... (see below).The
GEM_HOMEenvironment variable which will override the defaultINSTALLATION DIRECTORY.So, if you want to change
INSTALLATION DIRECTORY, then you have two choices for a fix:INSTALLATION DIRECTORY(determined at compile time).GEM_HOMEenvironment variable to any location that you prefer.A related env variable is
GEM_PATH, which will list all locations where Ruby will look for gems. The lookup folders will be listed ingem envunderGEM PATHS, and can be altered by yourself by setting theGEM_PATHenv variable on your machine.This way the combination of
INSTALLATION DIRECTORY,GEM_HOMEandGEM_PATH, determines how Ruby installs and where it finds its gems.
