我曾尝试重新安装ruby、重置rvm以及重新安装gcc，但这些都没有帮助。请告诉我是否有办法解决这个问题。以下是环境：

ruby -v 
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-darwin13.4.0]

rvm -v 
rvm 1.26.6 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

ruby-v
ruby 1.9.3p551（2014-11-13修订版48407）[x86_64-darwin13.4.0]
rvm-v
rvm 1.26.6（最新版本）作者：韦恩E.塞根，迈克尔·帕皮斯[https://rvm.io/]
除此之外，我想知道我是否可以学习一些材料来设置环境，例如：.bashrc文件中的每一行是什么意思

提前谢谢

在CLI中尝试以下步骤

brew tap homebrew/versions && brew install apple-gcc42

brew link --force apple-gcc42

ln -nsf $(which gcc-4.2) /usr/bin/gcc-4.2
然后尝试安装gem。

这有帮助吗@fvu您好，我已经安装了命令行工具，但仍然存在问题。您可能希望尝试通过尝试
ruby安装
从混合中删除RVM。
