  • A class import is missing: You have a missing class import. Try importing this class: `Illuminate\Support\Facades\Redis`.

      Illuminate\Redis\Connectors\PhpRedisConnector::createClient()

      Illuminate\Redis\Connectors\PhpRedisConnector::Illuminate\Redis\Connectors\{closure}()

2、此命令中使用到了缓存，使用 Redis 作为缓存驱动。编辑 .dev 文件，添加：REDIS_CLIENT=predis

CACHE_DRIVER=redis
REDIS_CLIENT=predis

3、再次执行命令：php artisan larabbs:calculate-active-user ，不再报错。如图2
