ruby - cannot load such file -- bundle/bundler/setup (LoadError)

Question

初学 ruby，尝试使用 zhaocai/alfred2-ruby-template 写 Alfred Workflow 时遇到以下错误：

bash$ ruby main.rb 
/Users/tranch/.rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- bundle/bundler/setup (LoadError)
    from /Users/tranch/.rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from main.rb:5:in `<main>'

Google 了下相关关键词，都说因为没装 bundler，但是反复验证了一番，证明确实是都安装了：

bash$ which gem
/Users/tranch/.rvm/rubies/ruby-2.2.0/bin/gemmaster*

$ gem list -d bundler
