Routing symfony2

Question

Can you tell why I get this output?

Cannot import resource "@TwigBundle/Resources/config/routing/errors.xml" from "C:\\xampp\\htdocs\\blog\\app/config/routing_dev.yml". Make sure the "TwigBundle/Resources/config/routing/errors.xml" bundle is correctly registered and loaded in the application kernel class. If the bundle is registered, make sure the bundle path "@TwigBundle/Resources/config/routing/errors.xml" is not empty.

This is the routing.yml:

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

This is 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

And composer.json :

这是一个symfony的2.6功能，看这里 。

Answer 2

是的，您应该将Symfony应用程序更新为Symfony 2.6或不使用此功能。
