laravel-vagrant command execution error (error report details included)

Question

What happened

Learning laravel some time ago, I installed a homestead on MAC (Sierra version 10.12), and everything was normal. Just after a certain boot, I executed homestead up and an error was reported. Executing homestead status also reported an error, and the error content was the same
But I executed homestead --version, homestead edit No problem
So I wondered if there was something wrong with the homestead environment, so I executed
vagrant box remove laravel/homestead
Thought Delete homestead and reinstall it. But vagrant also reported an error. So I wondered if there was something wrong with vagrant, so I wanted to delete vagrant, so I executed vagrant destroy and still got an error

The error message is as follows

When executing the homestead command, the following error is reported

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

Finally, I checked where the command reported the first error
/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

I don’t understand ruby ​​either, please take a look at it

The prompt means there is a problem with your configuration file. Check your homestead configuration file to see if there are any spaces or the like near the configuration items that have been deleted.

The best thing is to use diff to see the difference between the configuration file and the original version.

Please refer to this link. The line number of the error message is different, so you have to check it in your own configuration file.
