Laravel db 迁移 - renameColumn 错误 - 请求了未知的数据库类型枚举

I am using Laravel 4.2. I have the following library loaded in my composer.json

"doctrine/dbal": "2.4.*",

我创建了以下迁移:

class RenameDeliveryNotesColumnOnOrderHeaderTable extends Migration {

    public function up()
    {
        Schema::table('order_header', function(Blueprint $table)
        {
            $table->renameColumn('delivery_notes', 'packing_notes');
        });
    }

}

其中 delivery_notes 列类型为 text.

当我运行迁移时，我收到以下错误:
