Autotrust your RVM gemsets

One of the best features in RVM is having ability to use different gem sets for each project. It allows you to setup ruby env and gems isolation which makes development of different ruby and rails projects way easier.

To enable custom gemset you'll need to create an .rvmrc file under your application's root path with the following content:

rvm --create use ruby-1.9.2-p290@YOUR_APP_NAME

This will make RVM use a specific ruby version and a gemset. By default gemsets are not trusted. To autotrust all .rvmrc files add this into your user ~/.rvmrc file:

rvm_trust_rvmrcs_flag=1
