Edit

 namespace App\Providers;
 use Illuminate\Support\ServiceProvider;
 use Illuminate\Support\Facades\Schema;//新增
 class AppServiceProvider extends ServiceProvider{
     public function boot(){}
     public function register(){
         Schema::defaultStringLength(191);//新增
     }
 }
Copy after login

Then execute these two commands again

php artisan migrate
php artisan passport:install

     use Notifiable;
     use HasApiTokens;//新增

     protected $hidden = ['password', 'remember_token',];
 }

     protected $policies = ['App\Model' => 'App\Policies\ModelPolicy',];
     public function boot(){
         $this->registerPolicies();
         Passport::routes();//新增
