ruby-3.0.0 [ x86_64 ]

Answer 1

Updating RubyGems did the trick for me.
https://guides.rubygems.org/command-reference/#gem-update
gem update --system

Answer 2

This error must be for any rails application. Check the ruby and rails version from the Gemfile. In my case, it's ruby 3.1.2 and rails 7.0.4.
Reinstall or Install the dependencies again. Ruby 3.1.2 is already there in my system but I reinstalled in order to fix this issue.
Remove the bundler from /.rvm/gems/ruby-3.1.2/cache
rm -rf bundler-2.3.25.gem
My Gemfile.lock was bundled with 2.3.25
And remove ruby from /.rvm/gems
rm -rf ruby-3.1.2
Now the error will be changed when you install rails or bundle to something
invalid gem: package is corrupt, exception while verifying: wrong number of arguments (given 2, expected 1) (ArgumentError) in /Users/anjanasingh/.rvm/gems/ruby-3.1.2/cache/concurrent-ruby-1.1.10.gem
Now, uninstall ruby using rvm(Yes, rvm works in my case though I used rbenv for setting the ruby versions)
rvm uninstall "ruby-3.1.2
Install ruby
rvm install "ruby-3.1.2"
bundle your application
bundle install
Rails is still not there. So, install rails
gem install rails -v 7.0.4
I have tried with 'rbenv install 3.1.2' and reinstall, installenter image description here multiple times but it was not working with rbenv. Finally rvm worked.
