vagrant指令执行报错（内有报错详情）

Question

事情经过

前一段时间学习laravel在MAC（Sierra 版本10.12）上安装了一个homestead学习，本来一切正常。就在某次开机后执行 homestead up 就报错了，执行homestead status 也是报错，而且报错内容一样
但是我执行 homestead --version 、 homestead edit 就没问题
于是我就想是不是 homestead 环境出问题了 ，于是我执行
vagrant box remove laravel/homestead
想把 homestead 删除重装。但是 vagrant 也报错了。于是我就想是不是 vagrant 出问题了 于是我想把vagrant 删了 于是我执行 vagrant destroy还是报错了

报错信息如下

执行homestead指令的时候报错如下

    from /opt/vagrant/embedded/gems/gems/vagrant-1.8.6/bin/vagrant:174:in `<main>'

最后我查看了一下 指令第一次报错的地方
/opt/vagrant/embedded/lib/ruby/2.2.0/psych.rb:370:in `parse': (<unknown>): mapping values are not allowed in this context at line 2 column 3 (Psych::SyntaxError)

def self.parse_stream yaml, filename = nil, &block
368     if block_given?
369       parser = Psych::Parser.new(Handlers::DocumentStream.new(&block))
370       parser.parse yaml, filename
371     else
372       parser = self.parser
373       parser.parse yaml, filename
374       parser.handler.root
375     end

ruby我也不懂，请各位路过大神瞅瞅

提示说的意思是你的配置文件有问题，查看一下你的homestead配置文件，是不是配置项附近有什么空格之类的被删除了。

最好的就是你diff看一下配置文件和原版的区别。

这个链接你参考一下，错误提示的行号不一样，所以你要去你自己的配置文件里查。
