Guzzle和Symfony 3：未解決的基礎URL斷開作曲家安裝

Question

在我的Symfony 3應用程序中，我使用的是從其他api獲取數據的服務。

在這個服務中，我注入了「session」和一個字符串，代表了我的rest api的基礎url。

public function __construct(Session $session, $magentoRestUrl) 
{ 
    $this->session = $session; 
    $this->client = new \GuzzleHttp\Client([ 
     'base_uri' => $magentoRestUrl, // http://domain.com/rest/V1/ 
     'timeout' => 2.0, 
    ]); 

    $this->cache = new ApcuAdapter(); 

    $this->groupedIngredients = []; 
} 

到目前爲止，所有事情在我的本地機器上按預期工作。但現在，在與$magentoRestUrl部署過程不存在，我得到運行composer install --no-dev當這個錯誤：

... 
Writing lock file 
Generating autoload files 

[GuzzleHttp\Exception\ConnectException]                    
cURL error 6: Could not resolve host: domain.com (see http://curl.haxx.se/libcurl/c/libcurl-errors.html) 

Build step 'Execute shell' marked build as failure 
Finished: FAILURE 

我的問題是：爲什麼composer install觸發狂飲來解決$magentoRestUrl？是嗎，因爲它在服務類的構造函數中？

這裏是我的composer.json：

Symfony框架採用post-install-cmd和post-update-cmd腳本從composer.json由作曲家自動調用初始化緩存，打造bootstrap.php.cache等。

我認爲其中一個內部必須與依賴注入器一起工作，其中一個依賴關係還需要解析引發此錯誤的服務（這取決於您的服務配置）。
