Background knowledge: I installed node when installing yarn via brew before, but yarn doesn’t use the latest version of node well so I’m trying to switch to past version of node now.
node@8 seems to be a keg-only formula
Why do the homebrew developers decide to prevent us from using
brew link node@8
and ask us to use
brew link --force node@8
In other words, what’s so special about keg-only formula, that makes the developers decide to ask users to add
--force option to link them?
