composer clear-cache

取消配置：

查看镜像源

composer config -l -g

composer update 命令会直接把依赖的包更新到最新，会导致整个项目代码都是没有经过测试的不稳定代码所以一定要禁止使用该命令。

Composer设置忽略版本匹配的方法:does not satisfy that requirement

composer install --ignore-platform-reqs

 更新特定库

composer update symfony/flex --no-plugins

查看包的版本号

composer show --installed | grep redis

Warning: The lock file is not up to date with the latest changes in composer.json, you may be getting outdated dependencies, run update to update them.

update命令可以更新composer.lock中

composer update nothing

 全局安装，不需要json文件

composer require monolog/monolog
#更新或安装master
composer require monolog/monolog:dev-master
#更新或安装指定版本
composer require endroid/qr-code 1.9.3

移除依赖

composer remove monolog/monolog

自动加载包

require 'vendor/autoload.php'

use monolog/monolog;

调试模式

composer 命令增加 -vvv 可输出详细的信息，命令如下：

composer -vvv require alibabacloud/sdk

内存不足解决

php -d memory_limit=-1  /usr/bin/composer update monolog/monolog

        },
        "post-install-cmd": [
            "@auto-scripts"
        ],
