在RVM下安裝1.8.7 p358的問題

Question

得到Xcode rvm install 1.9.3後工作得很好。但是，rvm install 1.8.7會引發以下錯誤。

~ ☺ rvm install 1.8.7

任何想法如何解決？我試過rvm get head，安裝gcc-4.2並使用它，使用clang等，但似乎沒有任何工作。

Answer 1

確保滿足規定的全部要求：

rvm requirements 

包括的Xcode 4.1或osx-gcc-installer

運行（以修復損壞下載）：

rvm cleanup archives 

，然後再試一次：

rvm reinstall 1.8.7 

你有什麼理由爲什麼要用1.8.7？這是關於在生命的盡頭，如果這不是要求，應該使用1.9.3。
