我已经安装了 XCode 命令行开发工具，并且安装ruby-1.9.3-p448没有ruby-2.0.0-p247任何问题。

但是，当我这样做时，rvm install ruby-1.9.3-p194我得到一个错误：

Error running '__rvm_make -j 1',
please read /Users/michaelirey/.rvm/log/1382458979_ruby-1.9.3-p194/make.log
There has been an error while running make. Halting the installation.

这是该文件的输出：

我也试过： rvm install ruby-1.9.3-p194 --with-gcc=clang

以同样的结果...

您是否在您的环境中CC=gcc- 这可以解释问题 - ruby​​ 1.9.3 尚未准备好使用它（或clang）构建，请确保在尝试之前取消设置：

rvm get stable              # always update rvm first in case of problems
unset CC                    # unset CC to allow autodetection to work 
rvm install ruby-1.9.3-p194 # do not add extra flags

这应该允许 RVM 自动检测给定 ruby​​ 构建所需的适当 GCC，如果它仍然失败，则意味着您仍然有一些环境阻止自动检测或存在错误 - 在此处打开错误报告：https ://github.com/wayneeseguin /rvm/问题
