使用Composer异常“$ id必须是字符串或别名对象”的Symfony3安装

I have a problem with the installation of Symfony3 with composer, I followed the steps on the official web site but I have got the problem below and I can't run the symfony application

[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]

     $id must be a string, or an Alias object.
