处理 PHP 开发版本问题
在安装一个开源项目时,作者本地用了 PHP 7.1 进行开发,而我本地是 PHP 7.0, 于是悲剧发生了,出现了这样的错误:
requires php ^7.1 -> your PHP version (7.0.13) does not satisfy that requirement.
.
一、Composer 安装包
composer install 之后报错
vagrant@homestead:~/Code/sample$ composer install Loading composer repositories with package information Installing dependencies (including require-dev) from lock file Your requirements could not be resolved to an installable set of packages. Problem 1 - Installation request for doctrine/instantiator 1.1.0 -> satisfiable by doctrine/instantiator[1.1.0]. - doctrine/instantiator 1.1.0 requires php ^7.1 -> your PHP version (7.0.13) does not satisfy that requirement. Problem 2 - doctrine/instantiator 1.1.0 requires php ^7.1 -> your PHP version (7.0.13) does not satisfy that requirement. - phpunit/phpunit-mock-objects 2.3.8 requires doctrine/instantiator ^1.0.2 -> satisfiable by doctrine/instantiator[1.1.0]. - Installation request for phpunit/phpunit-mock-objects 2.3.8 -> satisfiable by phpunit/phpunit-mock-objects[2.3.8].
二、解决方法
删除 composer.lock
文件,重新执行 composer install
,这样就能重新生成 composer.lock
文件了。
composer 包自动加载后,会生成一个 composer.lock
锁文件,所以,在从GitHub拉取别人的代码后,需要对这个文件进行删除。
