2018-09-19git上拉取项目后，php版本问题

在从git上拉取项目后,在工程里
composer installer出现类似以下报错

Your requirements could not be resolved to an installable set of packages.
 
  Problem 1
    - Installation request for doctrine/instantiator 1.0.3 -> satisfiable by doctrine/instantiator[1.0.3].
    - doctrine/instantiator 1.0.3 requiresphp ~5.3 -> your PHPversion (7.0.3) does not satisfy that requirement.
  Problem 2
    - doctrine/instantiator 1.0.3 requires php ~5.3 -> your PHPversion (7.0.3) does not satisfy that requirement.
    - phpunit/phpunit-mock-objects 2.3.0 requires doctrine/instantiator ~1.0,>=1.0.1 -> satisfiable by doctrine/instantiator[1.0.3].
    - Installation requestfor phpunit/phpunit-mock-objects 2.3.0 -> satisfiable byphpunit/phpunit-mock-objects[2.3.0].

我本地的报错更加离谱，说是要修改php.ini
(我别的项目好好的修改个鬼啊)
其实这是因为项目的php版本与本地版本不匹配

可以使用此命令安装composer
composer install --ignore-platform-reqs
