Why does my Ruby 'ri' tool not return results in command prompt? [duplicate]
Although this question is old, nobody has yet provided a proper solution. I just ran into the same issue, and found the solution:
If you are using RVM:
rvm docs generate-ri # <- Just the ri docs, much fasterrvm docs generate # <- Everything (rdoc + ri)More info on managing RVM docs here:
https://rvm.io/rubies/docs
If not using RVM:
gem install rdoc-data# Regenerate system docsrdoc-data --install# Regenerate all gem docs (rdoc + ri)gem rdoc --all --overwrite # Regenerate all gem docs (ri only)gem rdoc --all --overwrite --ri --no-rdoc# Regenerate specific gem doc with specific versiongem rdoc gemname -v 1.2.3 --overwrite
