我在 Yosemite 上使用 rvm 安装 ruby 1.9.2 时遇到错误。有人可以帮助我吗？我更新了自制程序和rvm。我正在与其他人合作处理这个项目，所以我无法升级 ruby。我在下面放置了我的输出的链接。提前致谢！

我没有最好的答案，但似乎这是 OSX 处理 GCC 的方式中的一个错误......或者其他什么。我发现一个线程提到了补丁以及如何在此处安装它：https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61407 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61407
我还没有做，但我即将做，我会报告回来。不确定这是否是一个“答案”，但这也是我的问题，我需要尽快解决这个问题！
编辑：所有补丁都不起作用（可能是因为我不知道如何安装它们，但在我的终端中运行此行，然后执行rvm install 1.9.2似乎有效：
export PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:$PATH
