Class Magento\Sales\Model\Resource\Order\Collection does not exist

[ShoaibRehman89]

Hi all, 

I get " Class Magento\Sales\Model\Resource\Order\Collection does not exist" error whenever I run the setup:di:compile command. Is there a quick fix for this? 

I deleted Var/di, generation, cache and view_preproccessed directories before running this command. 

Any help is highly appreciated. 

Thanks

Shoaib

Hi @ShoaibRehman89,

Looks like your installation contains a very old extensions, as the correct class name is:

\Magento\Sales\Model\ResourceModel\Order\Collection

In order to support PHP 7, where "Resource" is a reserved word, Resource namespace was renamed to ResourceModel long time ago.

Hopefully, you will be able to apply quick fix by replacing all occurrences of Magento\Sales\Model\Resource\Order to Magento\Sales\Model\ResourceModel\Order
