composer require alibabacloud/sdk,PHP版本冲突解决

linux
PHP版本 8.0.8
laravel版本 8.80.0
执行命令 composer require alibabacloud/sdk 出错,提示以下问题

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - tymon/jwt-auth is locked to version 1.0.2 and an update of this package was not requested.
    - tymon/jwt-auth 1.0.2 requires php ^5.5.9|^7.0 -> your php version (8.0.8) does not satisfy that requirement.
  Problem 2
    - fzaninotto/faker is locked to version v1.9.2 and an update of this package was not requested.
    - fzaninotto/faker v1.9.2 requires php ^5.3.3 || ^7.0 -> your php version (8.0.8) does not satisfy that requirement.

You can also try re-running composer require with an explicit version constraint, e.g. "composer require alibabacloud/sdk:*" to figure out if any version is installable, or "composer require alibabacloud/sdk:^2.1" if you know which you need.

百度后找到这个文章 分享：[记一次]composer install --ignore-platform-reqs解决版本冲突,
执行命令 composer require alibabacloud/sdk - -ignore-platform-reqs
成功.

所以有个问题, 执行composer require时, 如果里面需要的依赖A已经存在,就会更新这个依赖A的版本吗,还是执行composer require时,会同时执行composer update?
