提示信息如上，composer安装很久了，也不知道改国内镜像没有，但是

composer require meabed/php-parallel-soap

这句话是我从官方仓库复制的，官方仓库也可以打开

一直提示没发现包

最后，在composer.json中，指定镜像为阿里云的，问题解决。




"repositories": {
  "packagist": {
    "type": "composer",
    "url": "https://mirrors.aliyun.com/composer/"
    }
  }

指定后，使用composer install，就安装成功了。
