=⇒ Caveats

By default, binaries installed by gem will be placed into:

/usr/local/lib/ruby/gems/3.1.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH, run:

echo 'export PATH=“/usr/local/opt/ruby/bin:$PATH”' » ~/.zshrc

For compilers to find ruby you may need to set:

export LDFLAGS=“-L/usr/local/opt/ruby/lib”

export CPPFLAGS=“-I/usr/local/opt/ruby/include”

For pkg-config to find ruby you may need to set:

export PKG_CONFIG_PATH=“/usr/local/opt/ruby/lib/pkgconfig”

=⇒ Summary

🍺 /usr/local/Cellar/ruby/3.1.2_1: 15,996 files, 41MB

=⇒ Running `brew cleanup ruby`…

Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.

Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
