我第一次使用 yii2，我想尝试 yii 迁移。问题：我创建了迁移文件

php yii migrate/create new_table

文件被创建。然后我将新表的详细信息输入到迁移文件中。当我运行时php yii migrate 出现错误

    require(__DIR__ . '/params.php'),
    require(__DIR__ . '/params-local.php')
    ); 
    return [
    'id' => 'app-console',
    'basePath' => dirname(__DIR__),
    'bootstrap' => ['log'],
    'controllerNamespace' => 'console\controllers',
    'components' => [
        'log' => [
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error', 'warning'],
                ], …
