ruby-on-rails - 终端 .bash_profile 搞砸了。如何还原？

Question

我正在关注如何在 Rails 上设置 ruby​​ 的教程。http://blog.parsalabs.com/blog/2013/08/27/setting-up-a-ruby-on-rails-4-development-environment-on-a-clean-mac-os-x-installation/

我跑了：

$ brew install rbenv

$ touch ~/.bash_profile

$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

现在我的终端已经停止工作了。

$ emacs ~/.bash_profile

-bash：emacs：找不到命令

当我打开一个新的终端窗口时。我收到以下消息：

  case "$command" in

    eval `rbenv "sh-$command" "$@"`;;
  *)
    command rbenv "$command" "$@";;

谢谢叶夫根尼·安菲洛夫耶夫，

解决方案是使用 TinkerTools 并删除我的 ~/.bash_profile

然后重新开始
