Magento 2.3.5 we found conflicting component dependencies

Question

I have tried every possible solution I could find on the internet.

From increasing the MEMLIMIT in the php.ini to 2G to removing the required tags in composer.json and so on.

This is a Vanilla install of CE 2.3.4 for the life of me I can not figure out what could be causing this.

I was actually trying to install the connector for Magento Store Manager and I figured it was an issue with the module but it does it with any extension.

Answer 1

Did you already checked the Release Notes of 2.3.5? In the Known Issues section it is stating the following:

Issue: Magento 2.3.5 does not support upgrading using the Web Setup Wizard from deployments running Magento 2.3.3 or earlier without first manually updating dependencies for magento/updater. You can upgrade using the Web Setup Wizard without issue from Magento 2.3.4 to Magento 2.3.5. Workaround: Users should run the following commands before upgrading using the Web Setup Wizard:

cd update

&& composer update

Answer 2

A bit of a stab in the dark but I have had strange issues in my installation until I started running composer starting with a call to a PHP executable and passing a memory limit.

In my case:

/usr/local/bin/ea-php72 -d memory_limit=3G  [full path to your composer executable]

Alas I haven't figured out how to edit the magento configs so the internal composer it calls now and then (eg: module:uninstall) also does the same so a few things still hang and need manual follow up

Answer 3

Did you check you PHP Version ? (php -v).

According to dev docs :

Supported PHP versions:

~7.2.0

~7.3.0

According to my experience, you should never use the last PHP version : the penultimate is always more stable than the last, so try PHP ~7.2.0.

Answer 4

I found the issue. Not sure it’s a fix, but I was finally able to figure out how to install modules via composer. I did it by accident, but inevitably it worked. Thank you for all the help everyone.
