Ruby no preset version installed asdf

The issue I faced here was:

  1. I installed a new version of ruby
  2. I added that version to my .tool-versions file
  3. I tried to run the application and was faced with the error No preset version installed for ...

I imagine others will face this issue with different plugins, but the answer for me was to reshim so that the exectuables were created for the Ruby version I wanted to use:

asdf reshim ruby 2.5.6

After that I was able to run ruby executables for Rbuy 2.5.6.
