Answer 1

您需要在安装 String filterExpression = "coloumnname.info.genres= :param"; Map valueMap = new HashMap(); valueMap.put(":param", "Drama"); ItemCollection scanResult = table .scan(new ScanSpec(). withFilterExpression(filterExpression). withValueMap(valueMap)); 之前手动删除过时的软件包spatie/db-dumper，这需要更新版本的db dumper软件包。

您可以从spatie/laravel-backup文件中删除spatie/db-dumper包，然后再安装。或者运行composer.json，然后继续安装备份包。

修改

从您的评论中可以清楚地看到，您已经安装了旧版本的软件包composer remove spatie/db-dumper。

修改2

由于您显然无法更新此软件包，因此这是我可以解释此问题的最简单方法。

运行spatie/laravel-backup

转到composer remove spatie/laravel-backup并删除第config/app.php行

运行Spatie\Backup\BackupServiceProvider::class

请按照包的进一步说明进行操作，其中还包括在app.php中添加服务提供商
