undefined method 'gem' for main:Object

I have to do development on several different machines (keeping them in sync is a real pain, so if you have any good advice please share) and when I went to do some rails work I kept getting this error everytime I'd try to do something:

undefined method `gem' for main:Object

It took me a little while to figure out, but I finally upgraded ruby gems

gem update --system

and things started working again.

Good call. I just ran into this myself and though wtf! Luckily you solved it already for me. Thanks brotha. Seems odd that you're on a .net blog writing about rails. Whatever.

Coming from the windows world the 2 best fixes are usually reboot or reinstall, so I figured well gem is in the error message let's see what I can do to that. So

gem --help

OOO, gem help commands lists all commands

I looked at a few commands there and eventually saw the -- system arg for update and figured I'd give it a try.
