安装包alibabacloud/cloudauth-20190307以后引用找不到类

当前使用的是 “会员电商系统pro v3.4”,   想实现 阿里云实名认证功能，安装了包  

composer require alibabacloud/cloudauth-20190307 3.10.0

composer require alibabacloud/darabonba-openapi 0.2.16

composer require alibabacloud/tea-console 0.1.0

单独执行php 文件是可以的， 放到接口端就提示找不到

"Class \"AlibabaCloud\\SDK\\Cloudauth\\V20190307\\Cloudauth\" not found"
