中间人服务器将无法启动，正则表达式内部无效

Question

我已经搬走了托管服务提供商，并重新安装了ruby和middleman。

当我运行bundle exe middleman server我得到：

我的Ruby知识很差，但是当我看代码时，看不到语法错误。 我看过s3_sync git中心代码，这段时间的代码没有改变。 我怀疑这是一个编码问题，但是我在尝试修复它时有些卡住。 您可以散发出的任何光都会很有帮助。

附加信息：我已经尝试过Ruby 1.8和1.9.3。 这是在Ubuntu 12.04上。

SyntaxError似乎在Middleman内部对此有所抱怨：

ProgressBar.create(total: paths.length)

/var/lib/gems/1.8/路径表示您正在使用Ruby1.8.X。 但是JavaScript样式的Hash表示法：

total: paths.length

在1.8中不起作用，您必须在其中使用:total => paths.length表示法。 看来您无法在1.8.7上使用该版本的Middleman，要么升级至1.9.3+，要么将Middleman降级至与较旧的Rubies兼容的版本。
