使用的是7.2.1的版本，composer报错如下：

guzzle7 最低支持的PHP版本是 7.2.5，所以你的 7.2.1 装不上。

另外 PHP7.2 都已经EOL了，PHP官方也都停止维护了，建议你升级至PHP7.4版本

升级是没有问题的。但是个人觉得最低支持7.0版本比较通用吧，毕竟很多老的项目一时半会没法升级到这么高的版本。

依赖的关键的加解密功能ext-openssl在PHP7.1上才支持aes-gcm；兼容php7.0会比较困难，要做许多适配，另外这个PHP7.2.5也是随guzzle7限制的，如果是低版本PHP可以尝试用wechatpay-guzzle-middleware。

了解了，非常感谢解答！
