嘗試使用RVM安裝Ruby 2.0.0時安裝rubygems失敗

Question

我正在處理我的第一個Rails應用程序。我剛剛從Rails 3.2.13更新到Rails 4，現在我試圖安裝ruby 2.0.0，但是我整天都陷入了同樣的錯誤。我在這裏發現了幾個關於SO和其他地方的問題，其中許多都有可接受的答案，但根本沒有任何解決方案適用於我。

最後，我最終完全刪除了所有ruby版本並完全刪除rvm，但即使試圖從頭重新安裝也會導致相同的錯誤。我在OSX 10.8.4上。

錯誤：

任何人有什麼我可以做些什麼來解決這個問題的任何想法？我試過解決方案this question但無濟於事。謝謝。

Answer 1

那麼，我終於設法修復它！對不起，如果我結束了污染SO。無論如何，我會回覆我的問題，以防有人遇到類似的問題，並在未來結束。

原來，根據Homebrew的說法，我搞錯了安裝libyaml「已安裝但未連接」。在嘗試this solution後我想通了。所以我卸載libyaml並用sudo rm -rf殺死它並重新安裝。我碰到了this problem，但接受的答案解決了它。在此之後，我使用穩定的紅寶石從頭開始安裝RVM，並且它終於奏效了！
