每当命令 Vagrant up 时，Vagrant 都无法找到该框。
我尝试显式添加该框但仍然无法正常工作，它显示此错误：
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Box 'ubuntu/bionic64' could not be found. Attempting to find and install...
default: Box Provider: virtualbox
default: Box Version: ~> 20210512.0.0
The box 'ubuntu/bionic64' could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp's Vagrant Cloud, please verify you're logged in via
`vagrant login`. Also, please double-check the name.
扩展的 URL 和错误消息如下所示：
