Problem installing fontawesome library via composer

Can be fixed by adding ||^2.0 in the composer.librairies.json require section:

        "require": {
          "composer/installers": "^1.2.0||^2.0"
        }

Replicated the same issue. #3 solution is working fine, adding a patch for the same changes.

Hi @mably , which version of drupal you are using because i am not getting this error at my end with drupal 10

Committed. Thank you!

@dheeraj-jhamtani I was on latest Drupal 10.1 I think.

I hade the problem because I have a custom composer configuration using merge-plugin that adds all dependencies it can find for every module existing composer.libraries.json file.

Something looking like this:

    "extra": {
        "merge-plugin": {
            "include": [
                "web/modules/contrib/*/composer.libraries.json",
                "web/modules/custom/*/composer.libraries.json",

No error without this specific configuration as, by default, composer won't parse the composer.libraries.json file.

Automatically closed - issue fixed for 2 weeks with no activity.

Having same issue but now with composer/installers v2.2:

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

Problem 1
- Root composer.json requires fontawesome/fontawesome 6.4.0 -> satisfiable by fontawesome/fontawesome[6.4.0].
- fontawesome/fontawesome 6.4.0 requires composer/installers ^1.2.0 -> found composer/installers[v1.2.0, ..., 1.x-dev] but it conflicts with your root composer.json require (^2.2).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Having same issue patch in #4 is not applying on Drpual 10.2.0
