致命错误：未捕获错误：在C：\ wamp64 \ www \ Hospital \ index.php中找不到类'Hospital \ Patient'：7堆栈跟踪：＃0 {main}

Question

这是我得到的错误：

  

致命错误：未捕获错误：未找到“医院\病人”类   C：\ wamp64 \ www \ Hospital \ index.php：7堆栈跟踪：＃0 {main}引入   第7行的C：\ wamp64 \ www \ Hospital \ index.php

这是index.php

<?php

require ("vendor/autoload.php");

use Hospital\Patient;

$patient = new Patient("asd","ad","asd","asd","asd");

var_dump($patient);

这是patient.php

<?php

namespace Hospital;

class Patient extends Person
{
     public function __construct($name, $age, $eyecolor, $height, $weight)
     {
        parent::__construct($name, $age, $eyecolor, $height, $weight);
     }
 }

这是composer.json

{
  "autoload":{
   "psr-4":{
    "Hospital//": ""
   }
  }
}

有人请求告诉我我做错了什么吗？ 如果你错过了信息，请告诉我，我是新手。
