rdiscount”错误：无法构建gem本机扩展。“

Question

这很有趣。我有rdiscount在一个rvm gemset中工作，但是当我尝试将它添加到另一个时，我会得到ERROR: Failed to build gem native extension.所以我试图从原始gemset中删除它，并重新安装它只是为了得到相同的错误。我不确定发生了什么事。我试图用Jekyll和Octopress构建它。我在OS X 10.7.5上。

这里发生了什么：

Using /Users/rachelnabors/.rvm/gems/ruby-1.9.2-p290 with gemset jekyll 
Can-Opener:RachelNabors.com rachelnabors$ gem install rdiscount 
Building native extensions. This could take a while...

同样的错误： https://github.com/rtomayko/rdiscount/issues/48

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

1.9.3应该做的很好！
