I don't use the RI or RDoc output from the gems I install in my machine or in the servers I handle (I use other means of documentation).
Every gem I install installs RI and RDoc documentation by default, because I forget to set
You just add following line to your local
~/.gemrc file (it is in your home folder)
or you can add this line to the global gemrc config file. Here is how to find it (in Linux)
strace gem source 2>&1 | grep gemrc
