rdiscount“错误:无法构建gem本地扩展。”

Question

这很有趣。我曾经在一个rvm gemset中工作，但是当我尝试将它添加到另一个中时，我得到了ERROR: Failed to build gem native extension.，所以我尝试从原始gemset中删除它，然后重新安装它，结果却得到了同样的错误。我不知道是怎么回事。我试着在Jekyll和Octopress版本中使用它。我使用的是OS X 10.7.5。

下面是发生的事情：

Using /Users/rachelnabors/.rvm/gems/ruby-1.9.2-p290 with gemset jekyll
Can-Opener:RachelNabors.com rachelnabors$ gem install rdiscount

同样的失败：https://github.com/rtomayko/rdiscount/issues/48

不支持Ruby 1.9.2。另请参阅：https://github.com/rtomayko/rdiscount/wiki/Support-Matrix

1.9.3对你来说应该很好！
