Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - yiisoft/yii2 2.0.x-dev requires bower-asset/punycode 1.3.* -> no matching package found.
    - yiisoft/yii2 2.0.13.1 requires bower-asset/jquery 3.2.*@stable | 3.1.*@stable | 2.2.*@stable | 2.1.*@stable | 1.11.*@stable | 1.12.*@stable -> no matching package found.
    - yiisoft/yii2 2.0.13 requires bower-asset/jquery 3.2.*@stable | 3.1.*@stable | 2.2.*@stable | 2.1.*@stable | 1.11.*@stable | 1.12.*@stable -> no matching package found.
    - Installation request for yiisoft/yii2 ^2.0.13 -> satisfiable by yiisoft/yii2[2.0.13, 2.0.13.1, 2.0.x-dev].

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.
 - It's a private package and you forgot to add a custom repository to find it

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

More information: https://insight.symfony.com/what-we-analyse/composer.security_issue_in_composer

The checker detected 2 security issues in package yiisoft/yii2 installed in version 2.0.0.0-beta
1) class yii\web\ViewAction allowed to include arbitrary files that end with .php.
2) JSON Data encoded for use in HTML was not safe to use in IE6/IE7, possible XSS attacks.
