Last night I tried the RM-Install product from Five Runs. It’s a multi-platform (Linux and Mac) Ruby on Rails Stack powered by BitRock. It is very similar to the Windows RubyStack offered by BitNami, but it is also supports a production install option.
I tried the development install and it was very easy to click next a few times and let it run. The very first thing I tried doing was updating the gems with “sudo gem update”. It failed giving me an error about not finding a file in require for some ELFClass. I’d never seen that before when updating gems, so I’m inclined to think that it may be something from within the RM-Install package.
So at the end of my first experience with the RM-Install stack, I think it’s a better solution to just create your own shell script for installing your Ruby/Rails environment.
