在OS X 10.9升级和自制安装后重新安装Ruby

在安装OS X 10.9和自制软件（sudo mv/opt/local〜/ macports）后，安装了Ruby 2.0的我的Rails 4.0.0停止工作。 Ruby仍然工作，但我无法加载所有的宝石来运行Rails了。所以我试图删除Ruby，Rails和RVM，然后重新安装。这是我尝试重新加载Ruby 2.0时得到的结果：在OS X 10.9升级和自制安装后重新安装Ruby

昨天我有一个问题，在一个干净的使用BREW和RVM安装，在我的bash的个人资料我的固定路径变量固定它。试试[这]（http://stackoverflow.com/questions/14175773/echo-path-doesnt-match-bash-profile） – creativereason

在您的.bash_profile文件中，它将位于您的主目录;试试这个，至少它为我工作： -

export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
