Firebase "Run firebase use default to activate project APP_NAME"

Question

It was successfully when deployed first time, now im trying to deploy again, shows an error:

Run firebase use default to activate project MY_APP_NAME 

Error:

No project active, but a project alias is available.

Answer 1

When you select a project during firebase init, an alias called default is created for you. To create a new alias, run:

firebase use --add 

Then Firebase CLI will ask you

Which project do you want to add? (Use arrow keys) 

This command allows you to select a Firebase project and give it a named alias. Alias definitions are written to a .firebaserc file inside your project directory.

Answer 2

At first should firebase use to make default alias.

After firebase use default to use default.

Then firebase deploy yahoo.. you can deploy
