You can download gems from https   rubygems org gems  or build you local gem via bundle and rack   eg     bundle gem yourGemName rake install   Take care of installing dependencies before installing actual gems    gem install --local  pathToFolder xxx-2 6 1 gem   Note  If using fluentd td-agent and ruby on same machine  Please make sure to use td-agent s td-agent-gem command  td-agent has own Ruby

Yup  when you do gem install  it will search the current directory first  so if your  gem file is there  it will pick it up  I found it on the gem reference  which you may find handy as well      gem install will install the named   gem  It will attempt a local   installation  i e  a  gem file in the   current directory   and if that fails    it will attempt to download and   install the most recent version of the   gem you want

Also  you can use gem install --local path to gem filename gem  This will skip the usual gem repository scan that happens when you leave off --local   You can find other magic with gem install --help

Well  it s this my DRY installation    Look into a computer with already installed gems needed in the cache directory  by default   Ruby Installation version  lib ruby gems  Ruby version  cache  Copy all    gems files  to a computer without gems in own gem cache place  by default the same patron path of first step   Ruby Installation version  lib ruby gems  Ruby version  cache  In the console be located in the gems cache  cd  Ruby Installation version  lib ruby gems  Ruby version  cache  and fire the gem install anygemwithdependencieshere  by example cucumber-2 99 0    It s DRY because after install any gem  by default rubygems put the gem file in the cache  gem directory and not make sense duplicate thats files  it s more easy if you want both computer has the same versions  or bloqued by paranoic security rules  v      Edit  In some versions of ruby or rubygems  it don t work and fire   alerts or error  you can put gems in other place but not get DRY    other alternative is using launch integrated command gem server and   add the localhost url in gem sources  more information in    https   guides rubygems org run-your-own-gem-server

you can also use the full filename to your gem file   gem install  full path to your gem   this works as well -- it s probably the easiest way

If you want to work on a locally modified fork of a gem  the best way to do so is  gem  pry   path     pry   in a Gemfile       where   pry would be the clone of your repository  Simply run bundle install once  and any changes in the gem sources you make are immediately reflected  With gem install pry pry gem  the sources are still moved into GEM PATH and you ll always have to run both bundle gem pry and gem update to test

If you create your gems with bundler     do this in the proper directory bundle gem foobar   You can install them with rake after they are written     cd into your gem directory rake install   Chances are  that your downloaded gem will know rake install  too
