当尝试使用以下命令从谷歌云项目中删除默认网络时：
gcloud compute networks delete default
返回以下错误：
`ERROR: (gcloud.compute.networks.delete) Could not fetch resource:
- The network resource 'projects/<PROJECT-NAME>/global/networks/default'
is already being used by 'projects/<PROJECT-NAME>/global/addresses/google-
managed-services-default'`
如何解决？
