Dont use fxp/composer-asset-plugin with composer 2+.
You need to switch to yiisoft/yii2-composer - it works OK with composer 2.
Remove with e.g. composer global remove fxp/composer-asset-plugin.
Then delete composer.lock and run composer update.
If you experience error with bower / npm directory, set custom alias in config/main.php e.g.:

'modules' => [ ... ],
'aliases' => [
		'@bower' => '@vendor/bower-asset',
		'@npm' => '@vendor/npm-asset',
],

error:

php composer.phar require kartik-v/yii2-icons “@dev”
./composer.json has been updated

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

Problem 1
- kartik-v/yii2-icons 1.4.x-dev is an alias of kartik-v/yii2-icons dev-master and thus requires it to be installed too.
- kartik-v/yii2-icons[dev-master, v1.0.0, …, v1.4.5] require yiisoft/yii2-jui * -> satisfiable by yiisoft/yii2-jui[2.0.0, …, 2.0.7].
- yiisoft/yii2-jui[2.0.0, …, 2.0.6] require bower-asset/jquery-ui 1.11.*@stable -> could not be found in any version, but the following packages provide it:
- ommu/gii Gii Generator Template from OMMU
- ommu/support Support Module from OMMU
- ommu/users Users Module from OMMU
- ommu/faq Frequency Asked Question Module from OMMU
- ommu/testimony Testimony Module from OMMU
- yuncms/framework The Yuncms Framework.
Consider requiring one of these to satisfy the bower-asset/jquery-ui requirement.
- yiisoft/yii2-jui 2.0.7 requires bower-asset/jquery-ui ~1.12.1 -> could not be found in any version, but the following packages provide it:
- ommu/gii Gii Generator Template from OMMU
- ommu/support Support Module from OMMU
- ommu/users Users Module from OMMU
- ommu/faq Frequency Asked Question Module from OMMU
- ommu/testimony Testimony Module from OMMU
- yuncms/framework The Yuncms Framework.
Consider requiring one of these to satisfy the bower-asset/jquery-ui requirement.
- Root composer.json requires kartik-v/yii2-icons @dev -> satisfiable by kartik-v/yii2-icons[dev-master, v1.0.0, …, 1.4.x-dev (alias of dev-master)].

The composer error log already gave you the answer. Check your minimum-stability version or your packages names and dependencies, specially the kartik-v/yii2-icons.
