Magento 2.2.4 – Fix Source Class “\amazonClient” for “amazonClientLogger” Generation Error

magento2.2.4

I am upgrading Magento 2.2.3 to 2.2.4 and got this error when running the command setup:di:compile after successfully running setup:upgrade.

[RuntimeException]
Source class "\amazonClient" for "amazonClientLogger" generation does not exist.

Weird but got fixed by running following commands in the order:

bin/magento deploy:mode:set developer
bin/magento cache:clean
bin/magento setup:di:compile
bin/magento deploy:mode:set production

setup/src/Magento/Setup/Model/Grid/Module.php

line 181

replace with

$item['moduleName'] = isset($item['moduleName']) ? $item['moduleName'] : $this->packageInfo->getModuleName($item['name']);

Always save copy of original file

Then refresh page (Module MANAGER) and should be working

I encountered the same issue. I am installing Magento 2.3.1 with Sample data. After changing the php version to 7.1 has worked for me.
