Trying to update Magento from 2.3.5 p1 to 2.4 but getting Invalid Argument Exception error

[kanchi777k3aa3]

Hi, I need help upgrading my Magento version from 2.3.5 p1 to the latest. I'm using Composer version 1 and php version 7.3.

I get a message saying Killed when I run 

COMPOSER_MEMORY_LIMIT=-1 composer update

What should I do?

you will need to update the composer plugin and composer before you can run this command

composer require magento/composer-root-update-plugin ~2.0 --no-update

composer update

Hi @kanchi777k3aa3 

Please see the Magento system requirements for the 2.4x version

Thanks for the response. I'll try updating to 2.4.0 first. That requires composer 1 so what I have should be ok. But running composer update still says Killed.
