symfony区域设置设置为en_US

我已经安装了三个区域设置包:

• JMSi18nRoutingBundle
• LuneticsLocaleBundle
• BeSimpleI18nRoutingBundle

我的config.yml是这样的:

jms_i18n_routing:
    default_locale: en
    locales: [en, fr, es]
    strategy: prefix
lunetics_locale:
    strict_mode: false
    allowed_locales: [en, fr, es]
    guessing_order:
        - query
        - router
        - session
        - browser
        - cookie
be_simple_i18n_routing: ~

一切都很顺利，只是我在日志中发现了一个错误:

[2015-08-02 01:16:48] request.CRITICAL: Exception thrown when handling an exception (Twig_Error_Runtime: An exception has been thrown during the rendering of a template ("I18nRoute "site_homepage" (en_US) does not exist.") in "TwigBundle:Exception:error.html.twig" at line 77. at /app/cache/prod/classes.php line 4528) {"exception":"[object] (Twig_Error_Runtime(code: 0): An exception has been thrown during the rendering of a template ('"I18nRoute '"site_homepage'" (en_US) does not exist.'") in '"TwigBundle:Exception:error.html.twig'" at line 77. at /app/cache/prod/classes.php:4528, Symfony''Component''Routing''Exception''RouteNotFoundException(code: 0): I18nRoute '"site_homepage'" (en_US) does not exist. at /app/cache/prod/classes.php:14728)"} []

在堆栈中我发现:[2015-08-02 01:16:49] app.INFO: Setting [ en_US ] as locale for the (Sub-)Request [] []但是，我不明白如何将区域设置设置为"en_US"。

我猜它来自LuneticsLocaleBundle的猜测，但是"en_US"应该匹配"en"，而不是"en_US"。

我的主要问题是我不知道如何跟踪这个。当我用我自己的设置连接到主页时，首先有"fr_FR"，绝对没有问题。

有没有人有测试的想法，我可以运行来解决这个问题?
