How to Build And Install Local Ruby Gem

Build Local Gem

Sometimes it’s really neat to customize or fork some Gems from GitHub, and this is how I install my modified version of a Gem locally and install it at will.

$ gem build bootstrappers.gemspec
Successfully built RubyGem
Name: bootstrappers
Version: 0.2.3
File: bootstrappers-0.2.3.gem
