Composer: Requirements could not be resolved in Yii2

Sometimes when you add more packages in yii2, you may get error like this:

Problem 1 - yiisoft/yii2-jui 2.0.6 requires bower-asset/jquery-ui 1.11.*@stable -> no matching package found. - yiisoft/yii2-jui 2.0.5 requires bower-asset/jquery-ui 1.11.*@stable -> no matching package found. - yiisoft/yii2-jui 2.0.4 requires bower-asset/jquery-ui 1.11.*@stable -> no matching package found. - yiisoft/yii2-jui 2.0.3 requires bower-asset/jquery-ui 1.11.*@stable -> no matching package found. - yiisoft/yii2-jui 2.0.2 requires bower-asset/jquery-ui 1.11.*@stable -> no matching package found. - yiisoft/yii2-jui 2.0.1 requires bower-asset/jquery-ui 1.11.*@stable -> no matching package found. - yiisoft/yii2-jui 2.0.0 requires bower-asset/jquery-ui 1.11.*@stable -> no matching package found. - Installation request for yiisoft/yii2-jui >=2.0.0 -> satisfiable by yiisoft/yii2-jui[2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6]. Potential causes: - A typo in the package name - The package is not available in a stable-enough version according to your minimum-stability setting see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details. Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

I don't know exactly why something like this happened, but I think the problem is related how we configure our composer when creating a new project. please cmmiw :D So to resolving this issue, what you have to do is run the following config in your cmd/terminal composer global require "fxp/composer-asset-plugin:^1.2.0" After that, you can try to run composer update again. In my case it solve my problem
