It seems either your intelliphense/VSCode is not in sync with composer, or the package is not yet installed therefore the trait is not recognized.

i use "composer update" and restart vscode ,now i think it's ok (maybe 5555) but now problem is i can't use assignRole()

what should i do??
I'm not sure why you're using auth()->user()->assignRole().
Normally calling auth()->user() is used when checking information, not when assigning information.
It would be better practice, and easier to debug, if you first retrieve the object (eg: $user = User::first();) and then do your role assignment (eg: $user->assignRole('something');)
