Ruby 使用最新命令行工具在Mavericks上运行Jekyll时出错

我正在尝试安装Jekyll并不断遇到问题。我使用的是OSX 10.9.2，使用的是ruby 2.1.1p76，我发现以下错误：

您对我可以尝试哪些方法来成功安装Jekyll有什么建议吗？

您说过您正在尝试使用ruby 2.1.1。但是您的日志显示ruby 1.8.7

考虑到这一点，你的机器上似乎安装了2颗红宝石。。。ruby 1.8.7由homebrew安装，ruby 2.1.1由rvm安装

显然，你也在ruby 1.8.7 gemset上安装了jekyll

因此，我建议您这样做：

gem uninstall jekyll

rvm use 2.1.1

gem install jekyll

看起来您正在使用ruby 1.8/Library/ruby/Site/1.8/ruby--version reports/usr/local/bin/ruby。我是用自制软件安装的。我应该怎么做？我建议您使用rbenv来管理您的ruby版本。这将是一个很好的基础，任何未来红宝石工作。好，我需要删除RVM，以便使用RBEV？这里有一个类似的问题，可能有助于解决问题的杰基尔，红宝石，和RBEV或RVM：
