composer works every where except one project

问题

I'm beginner in yii2. composer command works in every path in windows 10, but in one of my project's path composer command not works. Actually does nothing at all.

It's obviously in this image:

I don't know the the reason.

My composer.json:

    },

            "bower-asset-library": "vendor/bower"
        }
    }

}
