1、执行：vagrant up 时报错：The name of your virtual machine couldn’t be set because VirtualBox
is reporting another VM with that name already exists.。如图1

The name of your virtual machine couldn't be set because VirtualBox
is reporting another VM with that name already exists. Most of the
time, this is because of an error with VirtualBox not cleaning up
properly. To fix this, verify that no VMs with that name do exist
(by opening the VirtualBox GUI). If they don't, then look at the
folder in the error message from VirtualBox below and remove it
if there isn't any information you need in there.
VirtualBox error:
VBoxManage.exe: error: Could not rename the directory 'C:\Users\Lenovo\VirtualBox VMs\lt-settler_default_1614481073061_45587_1661751471272_95685' to 'C:\Users\Lenovo\VirtualBox VMs\homestead' to save the settings file (VERR_ALREADY_EXISTS)

2、删除 vagrant 后，再打开 VirtualBox GUI，确认是否存在，如果存在，再手动删除掉虚拟机。如图2

$ vagrant destroy

3、基于提示，删除掉目录：C:\Users\Lenovo\VirtualBox VMs\homestead。如图3
4、再次执行：vagrant up。不再报错。如图4
