获得 Xcode 后，一切rvm install 1.9.3正常。但是，rvm install 1.8.7会引发以下错误。

~ ☺  rvm install 1.8.7

知道如何解决吗？我已经尝试过rvm get head，安装 gcc-4.2 并使用它，使用 clang 等。但似乎没有任何效果。

确保满足以下规定的所有要求：

rvm requirements

包括Xcode 4.1或osx-gcc-installer

运行（修复损坏的下载）：

rvm cleanup archives

然后再试一次：

rvm reinstall 1.8.7

你有什么理由选择 1.8.7 吗？它即将结束，如果这不是必需的，则应使用 1.9.3 代替。
