説明
There's a nice plugin rbenv-communal-gems for rbenv to share the gem directories for minor versions, so e.g. all 2.6.x Rubies use the same gempath,2.5.x Rubies use another one, etc.
This is the standard approach used by Ruby itself, so this shouldn't cause any breakage and can save lots of space and headaches :)
It works by symlinking the gems folder inside the different Rubies:
$ ls -l ~/.rbenv/gems/
total 12

drwxr-xr-x 9 toupeira toupeira 4096 Mai 28 09:11 2.5.0
drwxr-xr-x 9 toupeira toupeira 4096 Mai 28 15:09 2.6.0
$ ls -l ~/.rbenv/versions/2.6.3/lib/ruby/gems
