经过了一番的几小时的摸索，于是我开始了我的报错解决之道：

step0:

安装composer:

要么①下载composer.phar 要么②安装composer install.exe for windows

step1：

Yii2 需要 composer-plugin-api 1.0 以上的版本
檢查 composer-asset-plugin 的版本或者查看一下有無安裝, 先確定有沒有或者有沒有超過1.0以上
如果都沒有的話使用 composer global require "fxp/composer-asset-plugin:~1.1.1" 去下載,

step3:

启用Packagist镜像

系统全局配置： 即将配置信息添加到 Composer 的全局配置文件 config.json 中。

composer config -g repo.packagist composer https://packagist.phpcomposer.com

[http://pkg.phpcomposer.com/] 

step4:

安装fxp/composer-asset-plugin

:composer require fxp/composer-asset-plugin

这时候中间会提示需要输入一个token：

 

并且：记住命令行要求github的token:

 所以去github：

 得到token后，复制过来

 等待安装fxp/composer-asset-plugin

完成后是这样的：
