composer强制安装插件

composer require第三方包的时候，发生某些错误，可以试用强制安装

带上引包的时候带上 --ignore-platform-reqs

composer require qiniu/php-sdk:^7.2  --ignore-platform-reqs

参数说明

--ignore-platform-reqs: ignore all platform requirements (php, hhvm, lib-* and ext-*) and force the installation even if the local machine does not fulfill these. See also the platform config option

忽略所有平台要求（php，hhvm，lib- *和ext- *）并强制安装，即使本地计算机不满足这些要求
