编译错误：无法声明类ResolveBindingsPass

Question

Whoops, looks like something went wrong.
(1/1) FatalErrorException

Compile Error: Cannot declare class 
Symfony\Component\DependencyInjection\Compiler\ResolveBindingsPass, because 
the name is already in use
in ResolveBindingsPass.php

我刚刚安装了一个项目，无论我做什么，即使清除缓存后，也会出现此错误。启动composer install时，它可以工作15秒 有人知道我怎么了吗？谢谢。
