Laravel:在迁移中显示控制台命令的输出？

use Illuminate\Support\Facades\Artisan;

class MyMigration extends Migration
{
    public function up()
    {
        $output = Artisan::call('my:command');
        // $output 变量将保存命令的输出内容
    }

    public function down()
    {
        // 迁移回滚操作
    }
}

use Illuminate\Support\Facades\Artisan;

class MyMigration extends Migration
{
    public function up()
    {
        Artisan::call('my:command');
        $output = Artisan::output();
        echo $output;
    }

    public function down()
    {
        // 迁移回滚操作
    }
}
