2、根源在于，需要将程序部署在华为云的ARM (鲲鹏)架构的云服务器上，因此，基础镜像换为一个支持 ARM 的镜像，进而 PHP 版本变化为：PHP 7.2.20。AArch64是Armv8-A架构中引入的64位状态。如图2

图2

[root@payment-7865946b4-v88ld /]# cat /etc/redhat-release
CentOS Linux release 7.8.2003 (AltArch)
[root@payment-7865946b4-v88ld /]# cat /proc/version

3、查看 composer.json。”php”: “>=7.3.0”,。如图3

图3

4、由于 /vendor 已经放入 Git 仓库中。编辑 composer.json：”php”: “>=7.2.0”,。如图4

图4

    "require": {
        "php": ">=7.2.0",
    },

5、将本地 Windows 环境的 PHP 版本切换至：7.2.14，与生产环境的镜像的 PHP 大版本：7.2.20 保持一致。如图5

图5

PS C:\WINDOWS\system32> php -v
PHP 7.2.14 (cli) (built: Jan  9 2019 22:23:26) ( ZTS MSVC15 (Visual C++ 2017) x64 )

6、删除目录：/vendor ，删除：composer.lock，重新执行：composer install。如图6

7、运行健康检查程序，一个 PHP 脚本，响应 200，未再报错。问题解决。如图7
