首先看报错信息如下：

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

解决办法，直接忽略版本就是了：

composer install --ignore-platform-reqs
# 忽略版本安装

composer update --ignore-platform-reqs
# 忽略版本更新
