Macos 端子断开| rbenv:未找到命令

我对OSX Mavericks上的终端体验不好。当我在启动终端时遇到这个错误时，我正在更新Ruby on OS X

-bash: rbenv: command not found

当我尝试

brew doctor

/usr/local/Library/Homebrew/global.rb:104:in `split': invalid byte sequence in UTF-8 (ArgumentError)
    from /usr/local/Library/Homebrew/global.rb:104:in `<top (required)>'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from /usr/local/Library/brew.rb:16:in `<main>'

当我完全退出终端并再次运行它时，我让它工作，但有错误

-bash: eval: line 4: unexpected EOF while looking for matching ``'
-bash: eval: line 5: syntax error: unexpected end of file
-bash: rbenv: command not found

运行

    $ brew doctor
    Warning: Homebrew's sbin was not found in your PATH but you have installed
    formulae that put executables in /usr/local/sbin.
    Consider setting the PATH for example like so
        echo export PATH='/usr/local/sbin:$PATH' >> ~/.bash_profile

因此，为了解决自制问题，我在路径文件中添加了“/usr/local/sbin”。

    $ brew doctor
    Warning: Homebrew's sbin was not found in your PATH but you have installed
