Github-Pages在本地运行Jekyll时出错

Question

我正尝试在本地运行我的Github-pages网站。我在另一台使用Windows x64上的Ruby2.1.0的机器上运行它。今天我想在运行Ruby 2.2.0的本地机器上运行。我在本地删除了我的repo，在nokogiri出现一些问题后运行了bundle install，我能够通过一个干净的bundle install。然后，我继续运行命令bundle exec jekyll serve -w。在运行此命令时，我收到以下错误：

/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>'

我开始相信这个问题与我的设置无关，而是与ruby 2.2.0上的jekyll不兼容。任何帮助都将不胜感激。

谢谢!

因此，在进一步挖掘之后，我遗漏了一个简单的步骤。在运行命令bundle install之后，我需要运行bundle update。一旦我这样做了，jekyll和其他依赖项的版本就会升级到正确的版本，然后我就可以运行我的bundle exec jekyll serve -w命令了，没有任何错误。

这似乎很奇怪，初始安装命令不会安装最新版本。
