            Schema::create('password_resets', function (Blueprint $table) {
                $table->string('email')->index();
                $table->string('token');
                $table->timestamp('created_at')->nullable();
            });
        }

You can set String Length manually by putting this

$table->string('name', 191); // You can put any number in exchange of 191

else

Put This in APP -> Providers -> AppServiceProvider

use Illuminate\Support\Facades\Schema;

public function boot() 
{
    Schema::defaultStringLength(191);
}
