在OS X 10.9升级和自制安装后重新安装Ruby

Question

安装OS X 10.9和自制软件（sudo mv / opt / local〜/ macports）后，使用Ruby 2.0的Rails 4.0.0停止工作。 Ruby仍然可以工作，但是我无法加载所有的gem来运行Rails。 因此，我尝试删除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：

    from setup.rb:45:in `<main>'

which looks like this on the command line:

任何帮助深表感谢！

在您的.bash_profile上，该文件将位于您的主目录中； 试试这个，至少对我有用：

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