Composer Your requirements could not be resolved to an installable set of packages

 

Composer install 时候报错：

Composer update 时候报错：

Your requirements could not be resolved to an installable set of packages

Problem 1

Root composer json requires topthink/framework 5 1.*, found topthink/framework [v5. 1. 41] in the lock file but not in remote repositories, make sure you av d updating this package to keep the one from the lock file

 

解决方案一：

composer update --ignore-platform-regs

使用强制安装更新

解决方案二：

更换composer镜像地址；

使用：

"repositories": {

        "packagist": {

            "type": "composer",

            "url": "https://packagist.phpcomposer.com"

        }

    }

 

或者：

"repositories": {

　　　　　"packagist": {

　　　　　　　　"type": "composer",

　　　　　　　　"url": "https://packagist.org"

　　　　}

}

 

切换 镜像地址后一般可以解决这个问题；

 

其他问题 ：

出现The "topthink/think-installer" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.1.0")

 

解决步骤：

①清除composer之前的镜像：composer config -g --unset repos.packagist

②更新thinkPHP版本：composer update topthink/framework  --no-plugins

③重新安装插件：composer update

 

其他解决方案：

①     切换项目文件夹

②     运行：composer config -g repo.packagist composer https://packagist.org
