What I did?

Installed tldrb via ruby using command:
gem install tldrb

I received next output:

And then I tried next:

tldr

And

tldrb

I got:

zsh: /usr/local/bin/tldrb: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: no such file or directory

ruby -v gives me 2.7.2 version and ls -a /System/Library/Frameworks/Ruby.framework/Versions/ gives me that:

2.6/

What should I do?

Yeah, that seems like something weird with your Ruby installation. Are you using something like e.g. RVM or rbenv? And if so, are you sure it's setup right?
