I just installed Ruby on my 12.04 machine by compiling from the tarball file I got from the official Ruby site.

I want to know why doing that was a bad idea if I don't plan on using multiple versions of Ruby anytime in the future?

What it boils down to is that ruby is a completely ecosystem, and it was not designed to have sudo in front of it for anything.

So it is recommended to use rvm (or rbenv or rbfu), since that way you should never have to use sudo.

I still haven't started using it. JUST installed it before posting haha. Can't seem to get the ruby command line working. I write 'ruby' and press enter and nothing happens. Was a lot easier in windows. Anyway, so you're saying I'll have to sudo everything? – Programming Noob Jun 28 '12 at 18:16
