Messages like Warning: require_gem is obsolete. Use gem instead. driving you nuts?

If you’re seeing tons of those messages like I’ve been and wondering what in the world that is all about. After Googling around I finally found a definitive answer on Jason Young’s Blog what it was all about.

What is it

Since rubygems 0.9.0 the command require_gem has been deprecated in favor of just plain gem. Part of the reasoning for it going the way of the dodo is tied to some
problems with autorequire. I don’t know any of the deep voodoo that powers rubygems but uh.. okay.. sure.

How to fix it

If you’re still getting these warnings you’re recommended to try re-installing all gems you might have installed if you have a 0.9.0 or lower installation. Happy Ruby Hacking.
