尝试使用 rvm 重新安装 ruby 并遇到此错误：
rvm reinstall all --force

There has been an error while running configure. Halting the installation.
我能做些什么来解决这个问题？提前致谢。

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
/opt/sm/pkg/active/bin/curl-config
/opt/sm/pkg/active/bin/ncurses5-config
/opt/sm/pkg/active/bin/ncursesw5-config
/opt/sm/pkg/active/bin/pkg-config

【问题讨论】：
-
如果您按照 rvm 的要求“阅读 /usr/local/rvm/log/ruby-1.9.3-p194/configure.log”，是否提供任何有用的信息？
-
好的，下一条线索：“配置：错误：C 编译器无法创建可执行文件”是 gcc 安装在您的系统上---它与 X 代码捆绑在一起吗？它在工作吗？或者您是否正在使用 Xcode 的替代品，例如：stackoverflow.com/questions/11436674/…
-
是的，GCC 已安装。消息已添加到上面的正文中。
-
我能想到的另一件事是您的 gcc 不是 Ruby 正在寻找的 gcc。你也可以运行
which gcc吗？
