执行 cd ~/Homestead && Vagrant up 命令失败

执行 cd ~/Homestead && vagrant up 后提示如下
Bringing machine ‘homestead-7’ up with ‘virtualbox’ provider…

==> homestead-7: Checking if box ‘lc/homestead’ version ‘8.2.1’ is up to date…

==> homestead-7: Machine already provisioned. Run vagrant provision or use the --provision

==> homestead-7: flag to force provisioning. Provisioners marked to run always will still run.

没有开启到虚拟机，这个是为什么？
