Magento setup:di:compile throwing class does not exist error message

[trevor_nally]

Hi,

If anyone can help, greatly appreciated.

Any way just ran setup:di:compile and the following error message has been thrown, no ida why! I have checked the app/code/Magento directory and cannot see any directories relating to any Inventory class. I am running Magento community version 2.3.5.

Class Magento\InventorySourceDeductionApi\Model\GetSourceItemBySourceCodeAndSku does not exist

Thanks in Advance!

kindly check if you have this module enabled 

php bin/magento module:status Magento_InventorySourceDeductionApi

this module is a part of MSI

If you are not using MSI then try disabling all the modules related listed here

Kindly Accept as a Solution if this works for you and give Kudos

Hi,

Thanks for your time...

The module you mention does not exist.

I tried disabling the modules that exist as part of the MSI, but none of them exist also.

Last time I worked on the site and ran setup:di:compile everything ran okay, all I can think is that composer has maybe added a denpendany that does not exis, but I don't think that is the case also!

Possibly after I started to install Facebook Pixel.

regards

Matt

Just to wrap things up, following some research I found that the missing inventory modules could be installed via downloading them from Github.

The version of Magento I was using required v1.1.6

https://github.com/magento/inventory/tree/1.1.6 .

After downloading and extracting the files were uloaded to the app/code/Magento directory.

chown -R www-data:www-data to modifiy file permissions after upload then:

bin/magento setup:upgrade

bin/magento setup:di:compile

bin/magento cache:clean

bin/magento cache:flush

As I am using the community edition I did not redeploy the static content, but this can be forced: bin/magento setup:static-content:deploy -f

Anyway problem solved

Overcome this compilation error you first need to check that all MSI  Modules are installed.

the above compilation error related to this magento module Magento_InventorySourceDeductionApi

so you can check the status of this module it installs or not using the below cmd command 

bin/magento module:status Magento_InventorySourceDeductionApi

if its disable then run 

php bin/magento module:enable Magento_InventorySourceDeductionApi

after enabling this module  I hope your compilation issue resolved. Thanks
