rdiscount」錯誤：無法構建gem本機擴展。「

Question

這很有趣。我有rdiscount在一個rvm gemset中工作，但是當我嘗試將它添加到另一個時，我會得到ERROR: Failed to build gem native extension.所以我試圖從原始gemset中刪除它，並重新安裝它只是爲了得到相同的錯誤。我不確定發生了什麼事。我試圖用Jekyll和Octopress構建它。我在OS X 10.7.5上。

這裏發生了什麼：

Can-Opener:RachelNabors.com rachelnabors$ gem install rdiscount

同樣的錯誤： https://github.com/rtomayko/rdiscount/issues/48

的Ruby 1.9.2不支持。另請參閱： https://github.com/rtomayko/rdiscount/wiki/Support-Matrix

1.9.3應該做的很好！
