更新到Rails 3.1失敗

Question

我剛剛安裝了帶有Xcode 4.1的OS X Lion。我使用Ruby 1.9.2和寶石版本1.5.0。當試圖從Rails 3.0.9升級到3.1時，出現以下錯誤：

$ ruby -v

$ rails -v

有沒有人知道這裏發生了什麼？

謝謝！

而不是做 「更新」 的，只是 「創業板安裝導軌-v 3.1」

UPDATE： 顯然軌3.1.0（activemodel的實際）取決於bcrypt-紅寶石。 3.1.1中應刪除此依賴關係（請參閱https://github.com/rails/rails/issues/2687）。

如果您不想等待，您需要解決bcrypt-ruby的構建問題。編譯器錯誤提示ruby與編譯器之間存在32位/ 64位不匹配。您是否將Lion安裝在Leopard上？如果是這樣，你可能不得不重建所有的rvm紅寶石和本地擴展寶石。

即使您想等待，您可能應該重新編譯，因爲您可能會再次遇到此類編譯器問題。作爲測試，請嘗試安裝一個本地gem，如：「gem install eventmachine」。如果你得到相同的錯誤，這是一個很好的指標，每個本地寶石都會遇到這個問題。 http://jtigger-learning.wikidot.com/gem-install-fails-on-building-native-extensions
