Composer 常见错误解决方案案例：执行 composer install 遇到错误：Your requirements could not be resolved
下面由composer教程栏目给大家介绍关于Composer常见错误及其解决办法，希望对需要的朋友有所帮助！Composer常见错误解决方案
执行composer install遇到错误：Your requirements could not be resolved to an installable set of packages. 这是因为不匹配composer.json要求的版本。
完整错误如下：
vagrant@homestead:/usr/share/nginx/html/laravel-blog$ sudocomposerinstall Loadingcomposerrepositorieswithpackage information Installingdependencies (includingrequire-dev) fromlockfile Yourrequirementscouldnot beresolvedto aninstallablesetofpackages. Problem 1 - Installationrequestfor doctrine/instantiator 1.0.3 -> satisfiablebydoctrine/instantiator[1.0.3]. - doctrine/instantiator 1.0.3 requiresphp ~5.3 -> yourPHPversion (7.0.3) doesnot satisfythatrequirement. Problem 2 - doctrine/instantiator 1.0.3 requiresphp ~5.3 -> yourPHPversion (7.0.3) doesnot satisfythatrequirement. - phpunit/phpunit-mock-objects 2.3.0 requiresdoctrine/instantiator ~1.0,>=1.0.1 -> satisfiablebydoctrine/instantiator[1.0.3]. - Installationrequestfor phpunit/phpunit-mock-objects 2.3.0 -> satisfiablebyphpunit/phpunit-mock-objects[2.3.0].
提示我的PHP 7版本太高，不符合composer.json需要的版本，但是在PHP 7下应该也是可以运行的，composer可以设置忽略版本匹配，命令是：
composerinstall --ignore-platform-reqs
或者
composerupdate --ignore-platform-reqs
再次执行composer命令可以正常安装包了。
如果提示警告：
Cannotcreatecachedirectory /home/vagrant/.composer/cache/repo/packagist.phpcomposer.com
