模板中的Twig函数“渲染”在哪里消失了？

我刚刚为我的Silex应用程序更新了我的依赖关系,现在突然我的模板之一因错误而失败：

Twig_Error_Syntax: The function "render" does not exist.

在执行作曲家更新之前,这工作正常.从作曲家的输出中,以下内容已更新：

在我的模板中运行的代码是：

{{ render (url('navigation')) | raw }}

我找不到任何暗示该功能已被弃用或已被其替代的东西.我不确定哪个更新引起了此问题,但我怀疑是Twig-Bridge.我正在使用Twig版本1.18.1.

我对这里的问题有些困惑,这给我带来了一些问题,所以任何帮助都将是很大的.

我承认这样一个事实,即我应该挂钩我正在使用的软件包的版本,以便可以更系统地测试升级.

谢谢,罗素

 }

我使用以下方法注册Twig和UrlGenerator服务：

$app->register ( new \Silex\Provider\UrlGeneratorServiceProvider () );
$app -> register (new \Silex\Provider\TwigServiceProvider(), array(
        'twig.options' => array("debug" => true)
    ));

$app['twig'] = $app -> share($app -> extend('twig', function($twig, $app) {
        $twig -> addExtension(new \Twig_Extension_Debug());
        return $twig;
    }));

Twig本身仍在工作,并且其中没有'{{render}}’的任何模板都可以正常工作.

解决方法:

我有同样的问题.在注册Web Profiler之前是否注册了HttpFragmentServiceProvider？它并不明显,但是文档中提到了here.它对我来说很好用.

问候
