在Vagrantfile文件裏作如下修改即可將其消失：

------------------------------------------------------------------------------

Vagrant.configure('2') do |config|
  config.vm.box = "hyperledger/fabric-baseimage"
  config.vm.box_version = ENV['USE_LOCAL_BASEIMAGE'] ? "0": baseimage_release # Vagrant does not support versioning local images, the local version is always implicitly version 0

  config.vm.network :forwarded_port, guest: 7050, host: 7050 # fabric orderer service
