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:
代码语言:javascript复制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].
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:
代码语言:javascript复制composer install --ignore-platform-reqs
composer update --ignore-platform-reqs
再次执行composer命令可以正常安装包了。
