10,865 PointsHow to install ruby and Rails 4 on MAC OS Mavericks
Hi Everyone,
It appears there is no "rails installer" for installing ruby on rails and the full development environment on MAC OS Mavericks. Can anyone point me to some good instructions on how to do so, perhaps with an installer or manually?
Thanks,
Joseph Hall

Courses Plus Student 7,323 PointsSure thing Joseph.
First of all, you'll want to get RVM. RVM allows you to easily install, manage and switch between multiple different versions of Ruby (or Ruby Gems) on your system. This is very useful when you need to make use of different versions for different projects.
I'd recommend reading through their installation guide, but the simple version is: run the following command from your command line and it will install RVM, Ruby and Rails in one go.
\curl -sSL https://get.rvm.io | bash -s stable --rails
If you require specific versions of Ruby or Rails, there are instructions in the RVM documentation for how to get these easily, or just comment here if you're stuck.
