I recently wanted to install a different Version of ruby and Rails on MacOS Big Sur 11.5 Beta. I Installed asdf via Homebrew. I wanted to run rails server but got the Message:
No preset version installed for command ruby
Please install a version by running one of the following:
asdf install ruby 3.0.2
or add one of the following versions in your config file at /Users/philippkorn/.tool-versions
ruby 3.0.1
When I try to run any asdf install ruby command (i.e. asdf install ruby latest) I get the following error message:
~ $ asdf install ruby latest (base)
Version not found
I tried reinstalling asdf with homebrew but the error persists...
I am facing same situation. It seems to be fixed soon.

Edit ~/.asdf/plugins/ruby/bin/install and apply this patch then the problem is fixed for me.
