How to make --no-ri --no-rdoc the default for gem

问题:

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 --no-ri --no-rdoc.

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

回答1:

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 the global gemrc config file. Here is how to find it (in Linux)

strace gem source 2>&1 | grep gemrc

回答2:

From RVM’s documentation:

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

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

---

Note: The original answer was:

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

This is no longer valid; the RVM docs have since been updated, thus the current answer to only include the gem directive is the correct one.

回答3:

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

or

gem: --no-document

回答4:

On Linux (and probably Mac):

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

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

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.

A oneliner for the windows 7 users:

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

回答8:

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

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:

:exit

You can check if everything is correct with this command:

sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit ~/.gemrc

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'
Gem::ConfigFile::SYSTEM_WIDE_CONFIG_FILE

See the original post on this over here.

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 http://rubygems.org

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 http://rubygems.org

For Windows users, Ruby doesn't set up .gemrc file. So you have to create .gemrc file in your home directory (echo %USERPROFILE%) and put following line in it:

gem: --no-document

As already mentioned in previous answers, don't use --no-ri and --no-rdoc cause its deprecated. See it yourself:

gem help install
