Ruby升級/從1.9.3-p194降級到1.9.3-p286

我剛剛通過rvm upgrade命令和gemset從ruby 1.9.3-p194升級到1.9.3-p286。現在，當我運行耙鐵軌上我的Rails應用程式升級它給了我下面的跟蹤：Ruby升級/從1.9.3-p194降級到1.9.3-p286

任何建議表示讚賞。如果它的ruby版本與ruby debug 19 gem衝突。那我該如何降級回1.9.3-p194。

如果您通過rvm進行安裝，您應該能夠切換回該補丁程序'rvm use ruby-1.9.3-p194'。也不是一個真正的答案，但你總是可以嘗試用pry進行調試，而不是:)。 – agmcleod

我想我只是嘗試一下;但允許升級的相同rvm命令也允許降級。所以下面的命令允許我降級到以前的版本：

rvm upgrade 1.9.3-p286 1.9.3-p194

它也遷移了寶石。順便說一句，我也發現降級後，我用的rake rails update命令有不正確的語法。因此，這是不正確的：

rake rails update --trace (incorrect)

這是正確的：

rake rails:update --trace (correct)

我沒有在升級後得到的錯誤再次，這意味着我很可能使用了錯誤的語法。
