Error on update from 2.3 to 2.8 and 2.7? I'm using drupal commerce 2.3 and want to update to commerce 2.8.

I just copied the files to the new folder and get the error:

PHP Fatal error:  Uncaught Error: Class 'CommerceGuys\Addressing\AddressFormat\FieldOverride' not found in C:\www\crypto-excel\modules\contrib\commerce\modules\store\src\Entity\Store.php:272

But when I go to :
 C:\www\crypto-excel\modules\contrib\commerce\modules\store\src\Entity\Store.php

This file is just there.

I tried the same to goto commerce 2.7, but then same error applies. 

Somebody any suggestion?
I just copied the files to the new folder


That's not how to update a Drupal 8 project - you need to use Composer.

Run composer update in your project root, and the old version of the address library (commerceguys/addressing), which is causing your current problem, will be upgraded alongside the modules.
