I have not been able to get readline working with the 1.9.3 preview
RVM. The results of my most latest attempt follow:
Readline was unable to be required, if you need completion or
install readline then reinstall the ruby.
You may follow ‘rvm notes’ for dependencies and/or read the docs
https://rvm.beginrescueend.com/packages/readline/ . Be sure you ‘rvm
remove X ; rvm install X’ to re-compile your ruby with readline
support after obtaining the readline libraries.
I did, by the way, try following the instructions at the referenced URI
(replacing “1.9.2” with “ruby-1.9.3-preview1”). No dice. Any
suggestions on how to resolve this problem would be appreciated.
