Would you like to try reinstalling the package instead [yes]?

Answer 1

Try these steps:
Delete vendor directory from your project.
Run composer clear-cache command.
Run composer install again.

Answer 2

Change your version for dektrium/yii2-user to the following in composer.json
"dektrium/yii2-user" : "^0.9.12",
and run composer update
try matching your composer.json to the following
"minimum-stability" : "dev",
"prefer-stable" : true,
"require" : {
"php" : ">=5.4.0",
"yiisoft/yii2" : "*",
"yiisoft/yii2-bootstrap" : "~2.0.0",
"yiisoft/yii2-swiftmailer" : "~2.0.0",
"dektrium/yii2-user" : "^0.9.12",
"dektrium/yii2-rbac" : "1.0.0-alpha#dev",
},
"require-dev" : {
"yiisoft/yii2-debug" : "~2.0.0",
"yiisoft/yii2-gii" : "~2.0.0",
"yiisoft/yii2-faker" : "~2.0.0",
"codeception/base" : "^2.2.3",
"codeception/verify" : "~0.3.1"
},
"config" : {
"process-timeout" : 1800,
"fxp-asset" : {
"installer-paths" : {
"npm-asset-library" : "vendor/npm",
"bower-asset-library" : "vendor/bower"
}
}
},
"scripts" : {
"post-install-cmd" : "php init --env=Development --overwrite=n"
}
Notice : that i have used config.fxp-asset.installer-paths rather than extra.asset-installer-paths that has been deprecated.
