How to make –no-ri –no-rdoc the default for gem install?

I don’t use RI or RDoc from the gems I install in my machine or in the servers I handle (I use other means of documentation), but every gem I install comes with RI and RDoc by default and I forget to set –no-ri –no-rdoc.

Is there a way to make those two flags the default?

You can specify default options using the .gemrc configuration file.

Documentation about gem configuration file

You just add following line to your local ~/.gemrc file (it is in your home folder)

gem: --no-document

or you can add this line to global gemrc config file, here is how to find it (in linux)

strace gem source 2>&1 | grep gemrc

On Windows XP the path to the .gemrc file is

c:/Documents and Settings/All Users/Application Data/gemrc 

and this file is not created by default, you should create it yourself.

# /home/{user}/.gemrc

:update_sources: true
:benchmark: false
:bulk_threshold: 1000
:backtrace: false
:verbose: true
gem: --no-ri --no-rdoc

From RVM’s documentation:

Just add this line to your ~/.gemrc or /etc/gemrc:

gem: --no-rdoc --no-ri 

The answer stated earlier:

install: --no-rdoc --no-ri 
update: --no-rdoc --no-ri 

but it got updated with the docs it was quoting – @mpapis

Step by steps:

To create/edit the .gemrc file from the terminal:

vi  ~/.gemrc

You will open a editor called vi. paste in:

gem: --no-ri --no-rdoc

click ‘esc’-button.

type in:


You can check if everything is correct with this command:

sudo /Applications/ ~/.gemrc

On Linux (and probably Mac):

echo 'gem: --no-document' >> ~/.gemrc

This one-liner used to be in comments here, but somehow disappeared.

Note that –no-ri and –no-rdoc have been deprecated according to the new guides. The recommended way is to use –no-document in ~/.gemrc or /etc/gemrc.

install: --no-document
update: --no-document


gem: --no-document

A oneliner for the windows users:

(echo install: –no-document && echo update: –no-document) >> c:/ProgramData/gemrc

On Windows7 the .gemrc file is not present, you can let Ruby create one like this (it’s not easy to do this in explorer).

gem sources --add

You will have to confirm (it’s unsafe). Now the file is created in your userprofile folder (c:/users/)

You can edit the textfile to remove the source you added or you can remove it with

gem sources --remove

As mentioned above, put gem: –no-document in your gem file. However, the system-wide gemrc will not always necessarily go into /etc/gemrc. If you are using RVM, or you have Ruby installed under /usr/local/bin, it needs to go in a different location. You can find this location by running irb and typing…

require 'rubygems'

See the original post on this over here.

One line to rule them all:

echo "gem: --no-document" >> ~/.gemrc
