Call to undefined method after upgrading to laravel 5.4

Question

I have tried to upgrade my project to laravel 5.4 from 5.3 today. I added

"laravel/framework": "5.4.*",

To my composer.json and run the command composer update and then composer dump-autoload and then tested my project. It gives me this error:

Error:

FatalThrowableError in 2154f392745gf102547be138a945a11b58e5649203.php line 2: Call to undefined method Illuminate\\View\\Factory::getFirstLoop()

Did I miss something?
