Github-Pages錯誤本地運行Jekyll

Question

我想在本地運行我的Github頁面網站。我已經在另一臺使用Windows x64上的Ruby 2.1.0的機器上運行它。今天我想在運行Ruby 2.2.0的家用機器上本地運行。我在本地拉回我的回購，在與nokogiri的幾個問題後跑bundle install我能夠通過一個乾淨的bundle install。然後我開始運行命令bundle exec jekyll serve -w。在運行此命令我收到以下錯誤：

/Users/<me>/.rvm/gems/ruby-2.2.0@global/gems/commander 4.1.6/lib/commander/runner.rb:385:in block in require_program': program version required (Commander::Runner::CommandError)

    from /Users/<me>/.rvm/gems/ruby-2.2.0/bin/ruby_executable_hooks:15:in <main>' 

我開始相信，這個問題是不是與我的設置，但與傑奇上紅寶石2.2.0不兼容的事情。任何幫助，將不勝感激。

謝謝！

所以經過一些挖掘，我錯過了一個簡單的步驟。運行命令bundle install後，我需要運行bundle update。一旦我做到了這一點，jekyll和其他依賴項的版本被提交到正確的版本，然後我能夠運行我的bundle exec jekyll serve -w命令沒有任何錯誤。

這似乎很奇怪，初始安裝命令不會安裝最新版本。
