@sidolov i put priority to p1 as you can’t crate a new magento project with composer 2.2

[giacmir]

Composer 2.2 has been released today. At this time Magento2 is not compatible with Composer 2.

[raumatbel]

You have to downgrade the version of composer to 2.1.4
Run this composer selfupdate -- 2.1.4. With the last version of composer 2.2, the installation fails.

In Magento cloud we have the version 2.1.14 and we have the same problem

[ssx]

In Magento cloud we have the version 2.1.14 and we have the same problem

If you pin it in .magento.app.yaml it'll work:

dependencies:
  php:
    composer/composer: '>=2.0 <2.2'

then clear your project's build cache.

[alanbort]

Hi, consider using the more generic '>=2.0 <2.2' for composer version in .magento.app.yaml:

dependencies:
    php:
        composer/composer: '>=2.0 <2.2'

[mbrioski]

As long there are versions like 2.1.14 having the same issue, i will go with :

dependencies:
  php:
    composer/composer: '2.1.4'

[Alexander-Pop]

changing composer version to '2.1.4' fixed this issue for us. TY

[gvasilakiss]

Same issue here, by changing the version to 2.1.4 fixed my installation.

[hostep]

Linking to two bugreports on composer's repo:

• composer v2.2.0 install fail on magento2-module with allowed plugin composer/composer#10390
• Composer 2.2 breaks Magento installations with create-project composer/composer#10384

Based on the comments in there, I'd expect the next version of composer to be released within a few days which will probably fix this problem.

[hostep]

This issue is now fixed in composer 2.2.1

Make sure to allow all the plugins it asks for during installation to be allowed though.

[manugentoo]

In my end. Composer version 2.1.2 worked well on Magento V2.4.2, V2.4.2-p1, V2.4.3, V2.4.3-p1

[hostep]

You'd probably want to update to at least composer 2.2.3 to avoid other crazy weirdness happening 😉
