solution for this? I am stuck on the same thing after upgrading from 2.2.7 to 2.3.5

[Bernard Robbins]

I'm also getting this error. I believe it's caused by a 3rd party module. 

[Bernard Robbins]

This was caused by running PHP7.1 on setup:di:compile instead of PHP7.3

I'm having the same problem.

Magento 2.3.6 to 2.3.7, php 7.3, composer update.  Fixed some memory issues, but than the composer ran and finished without problems.

The error occures when using   bin/magento setup:upgrade

Anyone has a fix???

Update: also php 7.4 does not solve my problem. Also removing all vendor packages and   composer upgrade  does not solve the problem.

[MedusaDelft]

I've managed to get a version of the site working. Not everything seems to show as was in v2.3.6, so I have more digging to do.

After making/updating my   composer.json   almost the same by copying lots of lines from the magento-2 github v2.3.7-branche(!) composer.json, I still got the error.

Solution: Then I found a laravel-problem which was similar with Psr/Container.  So I added the line   "psr/container": "1.0.0"   to my   composer.json   and run   composer update

Now   bin/magento setup:upgrade   gave a different error (!).  In   setup/src/Magento/Setup/Module.php   was an error at line 80.   I removed the trailing  ,   (comma) in the last line from the array_merge-command and the   bin/magento setup:upgrade  now worked. After entering the command   bin/magento maintenance:disable   I can see the front page again too. Now I just have to do more testing to see if everything works as supposed.

I have tried this solution but I got even more errors in the composer update.

I have tried adding "psr/container": "1.0.0" in Composer under "require":{ but this did not work either.

The following is wah I am getting

This error indicates an incompatibility between Laminas Service Manager and PSR-11 interfaces in Magento 2.3.7. To resolve, either update to the latest Laminas Service Manager v2 via Composer, or edit your composer.json to remap the incompatible interface name. Clearing caches and running setup upgrades after making Composer changes can also help fix the issue. If the problem persists, consider reverting to an earlier Magento version like 2.3.5-p1 that did not have this conflict.
