Rails printing out a bunch of unnecessary stuff

Question

When I do any command with rails or rake, it prints out tons of deprecation warning every single time. I am simply learning rails with the agile book... I do not need to wade through all this constantly.

Here is the output of "rake test". Please, can somebody tell me what this is and how to stop it?

Answer 1

It's a duplicate as the commenter (spender) said, but the simplest thing is to revert your rubygems to a less frustrating version until the dust settles

gem update --system 1.7.2 (or 1.6.2 even)
