So, what is you question? What did you do to get this error? Please add more context. – common sense
Same thing. Just updated composer.json as in upgrade guide and ran composer update. – Alexander Konotop
Hm... Of course it's not callable, there's no such method because I've accidently changed 5.4->5.3 instead of 5.4->5.5 in my composer.json. – Alexander Konotop

This would normally happen if the version of laravel in your composer.json file is under 5.5.

You will want to make sure you have:

"laravel/framework": "5.5.*",

In the require portion of the json. Sometimes, if you update through composer, it will load the package from the cache. You might want to delete your $PROJECT_DIR/vendor/* folder and then run:

composer update --prefer-source

Notice the output to see that laravel/framework is indeed at 5.5.*.
