路由符号2

你能告诉我为什么得到这个输出吗？

无法从"C:''examplep''htdocs''blog''app/config/routing_dev.yml"导入资源"@TwigBundle/Resources/config/routing/errors.xml"。请确保在应用程序内核类中正确注册并加载了"TwigBundle/Resources/cnfig/routing.errors.xml"捆绑包。如果捆绑包已注册，请确保捆绑包路径"@TwigBundle/Resources/config/routing/errors.xml"不为空。

这是路线。yml:

app:
    resource: "@AppBundle/Controller/"
    type:     annotation

这是routing_dev.yml:

> _wdt:
>     resource: "@WebProfilerBundle/Resources/config/routing/wdt.xml"
>     prefix:   /_wdt
> 
> _profiler:
>     resource: "@WebProfilerBundle/Resources/config/routing/profiler.xml"
>     prefix:   /_profiler
> 
> _configurator:
>     resource: "@SensioDistributionBundle/Resources/config/routing/webconfigurator.xml"
>     prefix:   /_configurator
> 
> _errors:
>     resource: "@TwigBundle/Resources/config/routing/errors.xml"
>     prefix:   /_error
> 
> _main:
>     resource: routing.yml

和composer.json:
