zsh: /usr/local/bin/colorls: bad interpreter: /usr/bin/ruby2.5: no such file or directory

Description

After I installing (gem install colorls) it gives me the following error:
zsh: /usr/local/bin/colorls: bad interpreter: /usr/bin/ruby2.5: no such file or directory

doing cat /usr/local/bin/colorls shows #!/usr/bin/ruby2.5 but ruby -v shows that I have ruby 3, not 2.5: ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-linux-gnu]

Linux Mint 21.1.
gem --version 3.3.5

I don't know why you would end up with ruby2.5 in the shebang. Are you using a Ruby version manager?

Does it help fixing the shebang line manually?
