问题
I forked the sinbook gem and added the git repo to my Gemfile. But the sinatra-authentication gem, which depends on sinbook, throws Gem::LoadError.
Why isn't my version of the gem being used?
Gemfile
source :rubygems
gem 'sinatra'
gem 'sinatra-contrib'
gem 'sequel'
gem 'jruby-openssl'
gem 'rack-flash'
gem 'sinbook', git: 'https://github.com/JamesGecko/sinbook'
gem 'sinatra-authentication'
gem 'json-jruby'
gem 'coffee-script'
gem 'therubyrhino'
error

Add require "bundler/setup" to app.rb. It it needed to load the bundled environment. More info may be found in the bundler documentation.
Since you're using Sinatra, you may also want to look into using config.ru.
