I went back and re installed Ruby 1.8.7 over 1.9.1 and it seemed to fix my problem but I wonder why I cant compile Heroku gem with 1.9.1? ---

The only thing I could find was this: [http://support.heroku.com/forums/42310/entries/54329](http://support.heroku.com/forums/42310/entries/54329) which asks for Ruby 1.9 support, but no reply from Heroku themselves. So, seems like you are stuck with 1.8.x for the moment. ---

You may try this approach: gem install --ignore-dependencies heroku gem install json\_pure You cannot install heroku because it depends on json gem, and by default non pure json gem gets installed and compilation fails. But if you manually install pure json gem it should work. At least it works for me, but my steps were a bit different: gem install heroku #find and delete json gem installed incompletely gem install json\_pure gem install --ignore-dependencies heroku ---

You should not have had to reinstall 1.8.7. Hivelogic’s tutorial doesn’t touch Apple’s Ruby – which is already 1.8.7. ## Best, Marnen Laibow-Koser [http://www.marnen.org](http://www.marnen.org) removed\_email\_address@domain.invalid
