Dear diary. Today I installed rbenv and actually read the whole readme to understand how it works. Looked up gem-install to get default config to where stuff is installed (this is not npm). Found rbenv-default-gems which might help not to run into “bundler is not installed” after upgrading ruby. Started at TryRuby but switched to go through all the Ruby String Methods.
It all feels incredibly right to do it this way idk ¯\_(ツ)_/¯
