• froala/yii2-froala-editor dev-master requires froala/wysiwyg-editor ^2.7.0 -> no matching package found.
• yii2mod/yii2-cms 1.9.1 requires froala/yii2-froala-editor dev-master -> satisfiable by froala/yii2-froala-editor[dev-master].
• Installation request for yii2mod/yii2-cms 1.9.1 -> satisfiable by yii2mod/yii2-cms[1.9.1].

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.
