我试图通过RVM更新的Ruby 1.9.3-P327。打字rvm install 1.9.3-p327后，我得到这个：运行configure时出错。暂停安装

然后，我检查的配置日志中ruby 1.9.3-p327/configure.log中，我看到这一点：

我已经安装了最新的Xcode 4.5.2以及通过Xcode安装CLT ..好像C编译器不工作，我不知道如何解决它。任何建议？
也许你试过已位于，但你最好的选择是谷歌的“配置：错误：C编译器不能创建可执行文件”。在那里你会发现很多这个问题的答案。你也可能会缺少'ld'（链接器..它是在谷歌的答案之一）。 – Casper
实际上，在发布此消息后，我使用了精确的字符串a。我注意到Xcode有些东西很腥，最后重新安装。有效。谢谢 – gregnowicki
