Issue

I want to install with composer, but this extension requires composer >=1.0.1 and many other extensions do not support this anymore, for example external-data:

Produces a stack trace and outputs:

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

  Problem 1
    - composer/installers v1.0.22 requires composer-plugin-api 1.0.0 -> found composer-plugin-api[2.3.0] but it does not match the constraint.
    - composer/installers[v1.0.23, ..., v1.8.0] require composer-plugin-api ^1.0 -> found composer-plugin-api[2.3.0] but it does not match the constraint.
    - Root composer.json requires mediawiki/external-data dev-REL1_39 -> satisfiable by mediawiki/external-data[dev-REL1_39].
    - mediawiki/semantic-compound-queries 2.2.0 requires composer/installers 1.*,>=1.0.1 -> satisfiable by composer/installers[v1.0.1, ..., v1.12.0].
    - You can only install one version of a package, so only one of these can be installed: composer/installers[v1.0.0, ..., v1.12.0, v2.2.0].
    - mediawiki/external-data dev-REL1_39 requires composer/installers ~2.1 -> satisfiable by composer/installers[v2.1.0, v2.1.1, v2.2.0].
    - Root composer.json requires mediawiki/semantic-compound-queries ~2.2 -> satisfiable by mediawiki/semantic-compound-queries[2.2.0].

Steps to reproduce the observation (recommendation is to use the sandbox):

This can be resolved by changing the requirements in composer.json, like in semantic-mediawiki:

"require": {
	"php": ">=7.3",
	"composer/installers": "^2.2.0|^1.0.1",
	"mediawiki/semantic-media-wiki": "~3.0|~4.0"
},

and with composer 1.10.26:

# sudo -u apache php ../composer.phar update --no-dev --ignore-platform-reqs

Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.
