Could not find local host metadata file 'host.json'

I want to use azure-functions-core-tools "func durable delete-task-hub" this command to delete taskhub under a storage account (I have current context's storage's connection string). But when I run this command, it reports:

Could I use this command to delete taskhub in azure portal?
