在Mac上修改Ruby环境变量

Ruby安装好后，执行ruby -v 发现还是旧的版本，原来是新版本的ruby没有添加到环境变量中去。

sh-3.2# echo $PATH 查看现有的环境变量
/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:
/Users/xujingbao/.rvm/bin:/Applications/
android-sdk-macosx/platform-tools/
sh-3.2# echo "export PATH=/usr/local/Cellar/ruby/2.0.0-p0/bin:$PATH"
将2.0版本的ruby 添加到bashprofile中
sh-3.2# source ~/.bash_profile
sh-3.2# ruby -v
ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.3.0]
sh-3.2# echo $PATH
/usr/local/Cellar/ruby/2.0.0-p0:/bin:
/usr/local/Cellar/ruby/2.0.0-p0/bin:
/usr/bin:/bin:/usr/sbin:
/sbin:/usr/local/bin:
/usr/local/git/bin:
/Users/xujingbao/.rvm/bin:
