Hi, even after restarting the terminal, the error is still there.

Error installing rails:
There are no versions of activesupport (= 7.0.0) compatible with your Ruby & RubyGems. Maybe try installing an older version of the gem you're looking for?
activesupport requires Ruby version >= 2.7.0. The current ruby version is 2.6.8.205.

How should I resolve this? Thanks!
