Butchered Ruby on Rails安装

Question

So first off, this is my first post on stackoverflow, so take it easy on me ;)

I'm a new Fedora user (f20) and I'm still in the early stages of getting used to linux. I tried to install Ruby on Rails (newest Ruby—2.1.1—and newest rails—4.1.0), using several guides I found online, which required for me to download and install several other packages. Several errors occurred towards the end of my installation so I thought I'd uninstall it and start from scratch using RVM which I hadn't done in the first place.

I tried removing the gems I installed using gem uninstall [gem_name] but I wasn't having any luck with many of them. So I decided to just sudo yum remove ruby in the hopes it would remove everything I had installed, but to my dismay the directory /usr/share/ruby still exists which makes me think that my uninstallation was incomplete.

Is there some why to completely remove any shred of ruby, rails, and gems from my computer so I can reinstall ruby on rails? Is it even necessary for me to do so in order to install a lower version of ruby (2.1.0)?

Thanks in advance.

Ok, after reading the comments I figured out the problem!

I ran a yum list | grep ruby yum list | grep ruby and similar searches and found that I had not, contrary to what I believed, removed all the packages I had installed. After deleting the remaining packages my usr/share/ruby folder vanished to the sound of my yipee's!

Thanks
