cannot load such file -- irb (LoadError)

[AlexanderZagaynov]

Problem description

CentOS Stream 9 doesn't install irb gem together with ruby package, which leads to the impossibility to run rails console commands, even if I prefer to use pry with byebug.

Workarounds:

• Install rubygem-irb system package. Drawbacks: it installs the old irb version, which spams console with warnings a lot.
• Include latest irb gem in the Gemfile. Drawbacks: one more useless dependency to keep in mind.

Expected behavior

rails console should open pry console without errors and warnings. Other commands, such as rails generate should work too.

Actual behavior

Without any irb
