我已經安裝了ruby和rails一段時間，並在一些項目上工作。最近，我安裝了Xcode 5開發人員預覽版，以便讓我的應用程序能夠準備好用於iOS 7.我只是提到了這一點，以防新Xcode搞砸了。RVM ruby安裝問題
在Rails項目目錄試圖
rake asets:precompile
，當我第一次注意到這個錯誤。它給出以下錯誤：
/Users/User/.rvm/bin/ruby:line 6：/Users/User/.rvm/bin/ruby：參數列表太長 /Users/User/.rvm/箱/紅寶石：行6：/Users/User/.rvm/bin/ruby：未定義錯誤：0
當我嘗試：
ruby -v
終端窗口提供在第一沒有響應時，終端標題在「bash」和「env」之間閃爍，但隨後顯示以下錯誤：
/Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Argument list too long
/Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Undefined error: 0
，當我嘗試
rvm get stable
我得到：

RVM reloaded!
最後，當我輸入：
rvm install ruby-2.0.0-p247
我得到：

，但它仍然與以前一樣。
據我所知我沒有改變系統的任何東西，我只安裝了新的Xcode。有人知道這裏有什麼錯嗎？不幸的是，這些rvm/ruby /終端命令，或者更確切地說，這個ruby安裝路徑權限的東西對我來說還是很新的。非常感謝您的寶貴時間！
謝謝，這是一個拯救生命的:) – Unrealist
