Problem 1
- yiisoft/yii2 2.0.7 requires bower-asset/punycode 1.3.* -> no matching package found.
- yiisoft/yii2 2.0.6 requires bower-asset/jquery.inputmask 3.1.* -> no matching package found.
- yiisoft/yii2 2.0.5 requires bower-asset/jquery.inputmask 3.1.* -> no matching package found.
- yiisoft/yii2 dev-master requires bower-asset/punycode 1.3.* -> no matching package found.
- yiisoft/yii2 2.0.x-dev requires bower-asset/punycode 1.3.* -> no matching package found.
- Installation request for yiisoft/yii2 >=2.0.5 -> satisfiable by yiisoft/yii2[2.0.5, 2.0.6, 2.0.7, 2.0.x-dev, dev-master].
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
