By default, RubyGems will install documents (ri, rdoc) together with gem when you install gem. It happens for both
gem install and installing with bundler.
Almost ruby developers will want to skip documents installation because they are usually useless with us and it takes time to install, specially when we use separated gemset for each project.
With single gem installation
When installing single gem with
gem install, we can add
--no-rdoc --no-rioptions to skip documents installation. So, command to install a gem will be:
gem install rails --no-rdoc --no-ri
By default and make bundler skip documents too
Above method is long, repeated everytimes we install a gem and bundler doesn't have these options to skip documents. I also beleive that almost ruby developers are using bundler to install gems.
To resolve this inconvenience, we can set these options as default when install gems by adding:
gem: --no-rdoc --no-rito
/etc/gemrc. From now, both single gem installation and bundler will skip documents without adding anythings to installation command
