Composer设置忽略版本匹配的方法,composer匹配
Composer简介
Composer 是 PHP 的一个依赖管理工具。它允许你申明项目所依赖的代码库,它会在你的项目中为你安装他们。Composer 不是一个包管理器。是的,它涉及 "packages" 和 "libraries",但它在每个项目的基础上进行管理,在你项目的某个目录中(例如 vendor)进行安装。默认情况下它不会在全局安装任何东西。因此,这仅仅是一个依赖管理。
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$ sudo 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 1.0.3 -> satisfiable by doctrine/instantiator[1.0.3]. - doctrine/instantiator 1.0.3 requires php ~5.3 -> your PHP version (7.0.3) does not satisfy that requirement. Problem 2 - doctrine/instantiator 1.0.3 requires php ~5.3 -> your PHP version (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 request for phpunit/phpunit-mock-objects 2.3.0 -> satisfiable by phpunit/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:
composer install --ignore-platform-reqs
or
composer update --ignore-platform-reqs
再次执行composer命令可以正常安装包了。
如果提示警告:
Cannot create cache directory /home/vagrant/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache Cannot create cache directory /home/vagrant/.composer/cache/files/, or directory is not writable. Proceeding without cache
这是在虚拟机中执行composer,提示这个目录没有可写权限,composer无法缓存下载的包,这样就每次都得重新下载,把目录改成可写可读即可。
sudo chmod -R 777 /home/vagrant/.composer/cache/files/
另外,在虚拟机中也设置composer为国内镜像,不然下载速度慢的要死,执行:
composer config -g repo.packagist composer https://packagist.phpcomposer.com
OK,大功告成。

When developing websites using CraftCMS, you often encounter resource file caching problems, especially when you frequently update CSS and JavaScript files, old versions of files may still be cached by the browser, causing users to not see the latest changes in time.

To further simplify the development process, I decided to use Composer to install and manage DUWA.io's PHP library - captaindoe/duwa.

Fortunately, by using sidus/doctrine-serializer-bundle, I successfully solved this problem, significantly improving the performance of the project.
