RVM紅寶石安裝問題

Question

我已經安裝了ruby和rails了一段時間，並參與了一些項目。 最近，我已經安裝了Xcode 5開發人員預覽版，以便為iOS 7准備好我的應用程序。我只是提到這一點，以防新的Xcode搞砸了它。

我首先在嘗試

rake asets:precompile

在rails項目目錄中。 它給出以下錯誤：

/Users/User/.rvm/bin/ruby：第6行：/Users/User/.rvm/bin/ruby：參數列表過長/Users/User/.rvm/bin/ruby：第6行：/ Users / User /.rvm/bin/ruby：未定義錯誤：0

當我嘗試：

ruby -v

終端窗口最初沒有響應，終端標題在“ bash”和“ env”之間閃爍，但隨后顯示以下錯誤：

/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!

最后，當我輸入：

rvm install ruby-2.0.0-p247

我得到：

但是它仍然和以前一樣。

據我所知，我沒有對系統進行任何更改，我只安裝了新的Xcode。 有人知道這是怎么回事嗎？ 不幸的是，這些rvm / ruby​​ / terminal命令，或者更確切地說，這個ruby安裝path-permission-rights的方法對我來說還是很新的。 非常感謝您的寶貴時間！

Answer 1

確保您的rvm是最新的：

rvm get stable

那么您需要運行：

rvm use ruby

這將確保您的環境設置正確，如果出現問題，它會顯示警告，您需要始終閱讀警告-並按照說明進行操作

使ruby持久用於下一個Shell會話使用：

rvm use --default ruby

它將創建default別名，該別名在rvm啟動時加載

Answer 2

看來錯誤發生在您的gem路徑中。 您確定@global gemset存在嗎？ 運行以下命令應該可以解決問題。

rvm gemset create global
