Question

Type error: Argument 1 passed to Symfony\\Bridge\\Twig\\Extension\\SecurityExtension::__construct() must be an instance of Symfony\\Component\\Security\\Core\\SecurityContextInterface, instance of Symfony\\Component\\Security\\Core\\Authorization\\AuthorizationChecker given, called in /path/to/project/var/cache/dev/appDevDebugProjectContainer.php on line 5090.

I still continue to have this error but when I update my composer

composer update

all work right.

How can I fix definitely it? Thanks.

SecurityContextInterface作为第一个参数SecurityExtension因为symfony的2.7已被弃用，并已在symfony中3后，您就可以选择降级到Symfony2的，或更新你的代码的symfony 3.在你的情况，我认为你已经升级您的symfony版本，但您忘记清除缓存 ： composer clearcache 。
