bundle和jekyll是什么关系？

Question

我在本地通过gem安装了jekyll和bundle 但是出现一个很诡异的问题：
我在jekyll项目文件夹下运行：

➜  zhangwei900808.github.io git:(master) ✗ jekyll --version
/usr/local/Cellar/ruby/2.3.1_2/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)
    from /usr/local/Cellar/ruby/2.3.1_2/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from /usr/local/lib/ruby/gems/2.3.0/gems/jekyll-3.3.1/lib/jekyll/plugin_manager.rb:34:in `require_from_bundler'
    from /usr/local/lib/ruby/gems/2.3.0/gems/jekyll-3.3.1/exe/jekyll:9:in `<top (required)>'
    from /usr/local/bin/jekyll:23:in `load'
    from /usr/local/bin/jekyll:23:in `<main>'

居然会报错，请问下这是为什么？？？
