錯誤注入教義和定製服務

Question

當我有在Symfony3依賴注射的一個問題：

這是我services.yml

some_service: 
    class: StagingBundle\Service\SomeService 
    arguments: ['@doctrine'] 
    arguments: ['@test.other_service'] 

這是SomeService.php

public function __construct($doctrine, SomeService $someService) 
{ 
    $this->doctrine=$doctrine; 
    $this->someService=$someService; 
} 

的構造

運行我的控制檯命令時出現以下錯誤：

[Symfony\Component\Debug\Exception\ContextErrorException] 
Catchable Fatal Error: Argument 2 passed to stagingBundle\Service\SomeService::__construct() must be an instance of StagingBundle\Service\OtherService, none given, called in /var/www/projects/myApp/var/cache/dev/appDevDebugProjectContainer.php on line 1141 and defined 

爲什麼會發生這種情況，我該如何解決？

「論據」是一個數組，只能有一次，所以它應該是這樣的

some_service: 
    class: StagingBundle\Service\SomeService 
    arguments: ['@doctrine', '@test.other_service']
