I successfully installed ruby version to 2.7, but ruby -v doesn't want to update. See output below:
ā ~ ruby -v
ruby 2.6.8p205 (2021-07-07 revision 67951) [universal.arm64e-darwin21]
Verify that Ruby 2.7 has been installed:
ā ~ brew install ruby@2.7
Warning: ruby@2.7 2.7.6_1 is already installed and up-to-date.
To reinstall 2.7.6_1, run:
brew reinstall ruby@2.7
What am I missing?
Type which ruby to find out where it's getting that executable from.
$ which ruby
/opt/homebrew/opt/ruby/bin/ruby
homebrew will put it in /opt/homebrew/opt/ruby/bin/ruby as shown there, but if that's not in your path then it will get the system ruby.
$ which ruby
/usr/bin/ruby
In that case you need to add the homebrew ruby bin directory to your PATH. I have this in my .bashrc:
export PATH="/opt/homebrew/opt/ruby/bin:/opt/homebrew/lib/ruby/gems/3.0.0/bin:$PATH"
