Uninstall Ruby, rbenv and homebrew and reinstall Ruby on Rails with RVM on MAC

Question

I'm very new to RoR specially on Mac. I have installed it many times on Ubuntu with RVM and I'm very comfortable with that. Here is what happened on Mac:

I went through instructions as explained here http://goo.gl/zsHcCC then when I got to the point to install Rails with " gem install rails " I got this error:

Error installing rails: ERROR: Failed to build gem native extension.

Now I want to roll-back everything and uninstall rbenv and it's ruby versions and reinstall the Ruby On Rails environment using RVM.

I tried to find how to uninstall Homebrew, RBENV and Ruby, but no success.

Thank you. Sia

Answer 1

Homebrew or Rbenv are very good tools to have as a dev, I would think twice before removing either.

In this case I doubt they are at fault.

Can you confirm you have installed the GCC command line utils for OSX by running $ xcode-select --install in your terminal.

Here is a useful post explaining that process but I find that command generally works fine for me.

If this succeeds what does your $ gem install rails output next?

Answer 2

If you are very new you and you don't need specially the last version of Ruby. You can use Rails Installer http://railsinstaller.org/fr-FR .
