當我在symfony2.0中運行init：acl時，你已經請求了一個不存在的服務「security.acl.dbal.connection」

Question

我得到這個錯誤，任何人都知道如何解決它！

You have requested a non-existent service "security.acl.dbal.connection" 

Answer 1

您需要在您的應用程序中啓用ACL支持。該行添加到您的security.yml配置文件：

acl: 
    connection: default 

然後再次運行php app/console init:acl。

Answer 2

既不適合我。這項服務實際上是不可用的...

Answer 3

只是爲了高擡頭，acl關鍵字應該放在security關鍵字後面的行上。如果你只把

acl: 
    connection: default 

在你security.yml文件的頂部，你可能會得到這個錯誤。我正在引用它，以便人們可以通過使用錯誤搜索來進入該主題。

[Symfony\Component\Config\Exception\FileLoaderLoadException]   
    Cannot import resource "/home/jupiter/symfony/cupon/app/config/secu 
    rity.yml" from "/home/jupiter/symfony/cupon/app/config/config.yml". 
    (There is no extension able to load the configuration for "acl" 
    (in /home/jupiter/symfony/cupon/app/config/security.yml). Looked for 
    namespace "acl", found "framework", "security", "twig", "monolog", 
    "swiftmailer", "assetic", "doctrine", "sensio_framework_extra", "ci 
    udad", "usuario", "tienda", "oferta", "backend", "ideup_simple_pagi 
    nator", "web_profiler", "sensio_distribution")  


    [Symfony\Component\DependencyInjection\Exception\InvalidArgumentException] 
    There is no extension able to load the configuration for "acl" (in

    ad", "usuario", "tienda", "oferta", "backend", "ideup_simple_pagina   
    tor", "web_profiler", "sensio_distribution"  

所以只要確保acl之後security關鍵字：

security: 
    acl: 
     connection: default
