[InvalidArgumentException]

## 原因 ##

下载的composer版本太高，2.1.x版本，但这个插件不支持2.x的，必须用1.x的。  
重新去composer官网下载 1.x的composer ，重新执行

wget https://getcomposer.org/download/1.10.22/composer.phar
    php composer.phar global require "fxp/composer-asset-plugin:~1.4" -vvv
    composer.phar install -vvv

## 下载报错 ##

[Composer\Downloader\TransportException]                                    
      Content-Length mismatch, received 136823 bytes out of the expected 1751254

继续解决：

# 调大缓存
    php composer.phar config --global cache-files-maxsize 1024
    
    # 使用华为镜像
    composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

## 问题解决 ##

其实问题根源在于这个插件 `fxp/composer-asset-plugin` 不支持2.x版本的composer导致，目前对方还没进行任何更新。

**更新于2021/07/14**  
最正确的解决办法是就是重新安装，删除composer.json，重新安装。  
composer2.x不需要引入 fxp依赖，直接解决这些问题，fxp作者估计是看到composer2.x不再依赖，所以不再更新维护了。
