Answer 1

According to the official Laravel 7.x documentation, you can solve this quite easily.

Update your /app/Providers/AppServiceProvider.php to contain:

use IlluminateSupportFacadesSchema;

/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    Schema::defaultStringLength(191);
}

Alternatively, you may enable the innodb_large_prefix option for your database. Refer to your database's documentation for instructions on how to properly enable this option.
