  Problem 1
    - Root composer.json requires infection/infection ^0.13.4 -> satisfiable by infection/infection[0.13.4, 0.13.5, 0.13.6].
    - infection/infection[0.13.4, ..., 0.13.6] require php ^7.1.3 -> your php version (8.1.10) does not satisfy that requirement.
  Problem 2
    - phpunit/phpunit[7.5.1, ..., 7.5.20] require php ^7.1 -> your php version (8.1.10) does not satisfy that requirement.
    - Root composer.json requires phpunit/phpunit ^7.5.1 -> satisfiable by phpunit/phpunit[7.5.1, ..., 7.5.20].

查看了下资料说是php版本不符,打开composer.json发现代码只要求大于7.0.0可仍然报这个错误,不用太较真执行如下代码之后在运行之前的代码就ok。

composer install --ignore-platform-reqs
# 或者

composer update --ignore-platform-reqs
