YII_ENV being ignored when including config

I have setup a new Yii2 advanced instance and ran init to set my local environment to dev. However the config files in environments/dev/* are being ignored. Is there something else I need to do?


download yii2 from https://github.com/yiisoft/yii2/releases/download/2.0.15/yii-advanced-app-2.0.15.tgz

after unzipe your file , open CMD and type composer then init
