问题是什么？

解决方法 首先,我尝试了irb中的RegEx：

$irbirb(main):001:0> /(?:"|')(?<Title>[^"']+)?(?:"|')\s+(?:"|')(?<alt>[^"']+)?(?:"|')/=> /(?:"|')(?<Title>[^"']+)?(?:"|')\s+(?:"|')(?<alt>[^"']+)?(?:"|')/irb(main):002:0>

我没有错误,但后来我发现服务器上的默认ruby版本是1.8.7.

我从rvm中选择了ruby-1.9.3-p551并将其激活.

我做了以下事情：

rvm use ruby-1.9.3-p551bundle installbundle exec rake generate

这解决了我的错误.
