Typo3 10 composer
Aimeos 21.4.13

Good Morning
Since the extension aimeos / ai-payments is no longer supported for TYPO3 10, I am facing a problem.
I should integrate Postfinance into the shop as a payment provider.

Is there a way to integrate the bummzack / omnipay-postfinance module?

aimeos/ai-payments extensions can be used without problems in TYPO3 10+ composer setups

I tried to integrate the extension several times on different websites. Without success.

This is the output from "composer req aimeos/ai-payments":

Your requirements could not be resolved to an installable set of packages.

Installation failed, reverting ./composer.json to its original content.

Can you post your composer.json? Your problem is that some Aimeos packages are pinned to 2021.04 there so installing ai-payment:2021.07 fails. You have to make sure that the other packages can be upgraded as well. Furthermore, you need composer 2.1+ for Aimeos 2021.07+

Thank you for your reply
I've tried the installation in several ways:
New website with "composer req aimeos / aimeos-typo3"
New website with "composer req aimeos / aimeos_dist"
New website directly with "composer req aimeos / ai-payments"
The installation failed for all of them

Here my composer.json file:

What's the output of "composer -V"? It must be version 2.1+

Now I tested this on a fresh website with Bootstrap Package:
"composer update" - Aimeos is now on version 21.7.2
"composer req aimeos / ai-payments" - results in the following error:

> Aimeos \ Aimeos \ Custom \ Composer :: install

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

[ErrorException]

Composer is version 2.1.5

Can you please try:

Thank you very much, the installation is done

I have just one more note:
With Aimeos 2021.07.2 (not dev) I couldn't install any further extensions. I had the same error message as described above (Script Aimeos \ Aimeos \ Custom \ Composer :: install handling the post-update-cmd event terminated with an exception)
