[Solved] Unable to install gii

Hello,

I’m unable to install gii. Composer says there is a problem with minimum-stability:

I tried to switch minimum-stability from dev to stable in composer.json.

In this case composer says:

My composer.json file is attached.

Could you help please? Thanks

you have two yii2-gii lines in composer.json

gii is installed by default, you not need install it manually.
