Que s'est-il passé

Il y a quelque temps, j'ai appris Laravel et installé un homestead sur MAC (Sierra version 10.12) Tout fonctionnait bien. Exécutez-le simplement après un certain démarrage 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 destroyIl signale toujours une erreur

Le message d'erreur est le suivant

Lors de l'exécution de la commande homestead, l'erreur suivante est signalée

Enfin, j'ai vérifié où la commande a signalé la première erreur
/opt/vagrant/embedded/lib/ruby/2.2.0/psych.rb:370 : dans `parse' : (<unknown>) : valeurs de mappage ​​ne sont pas autorisés dans ce contexte à la ligne 2, colonne 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

Je ne comprends pas non plus Ruby, s'il vous plaît, jetez-y un oeil
