Question

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.

Answer 1

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

Answer 2

I had same Issue, While installing zip with sample data.

I've resolved it my PHP Version to 7.1.x

Before PHP was 7.0.x, Don't know why Magetnto 2.2.4 doesn't seems to be work with PHP 7.0.x.

As After i switched to 7.1.x it installed successfully..

Hope it will help others..!!
