事情經過
前一段時間學習laravel在MAC（Sierra 版本10.12）上安裝了一個homestead學習，本來一切正常。就在某次開機後執行homestead up 就報錯了，執行homestead status 也是報錯，而且報錯內容一樣
但是我執行homestead --version 、 homestead edit 就沒問題
於是我就想是不是homestead 環境出問題了，於是我執行
vagrant box remove laravel/homestead
想把homestead 刪除重裝。但 vagrant 也報錯了。於是我就想是不是 vagrant 出問題了 於是我想把vagrant 刪了 於是我執行 vagrant destroy還是報錯了
報錯訊息如下
執行homestead指令的時候報錯如下

最後我查看了一下指令第一次報錯的地方
/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，請各位路過大神瞅瞅

提示說的意思是你的配置文件有問題，查看一下你的homestead配置文件，是不是配置項附近有什麼空格之類的被刪除了。
最好的就是你diff看一下設定檔和原版的差別。
這個連結你參考一下，錯誤提示的行號不一樣，所以你要去你自己的設定檔裡查。
