Can’t active this plugin using self-created storefront child theme

Replies: 1

I’m creating storefront child theme by myself. A very basic child theme, a functions.php and style.css file. The child theme runs without a problem.

But when I try to activate this plugin, it says:
"Sorry, you can’t activate this plugin unless you have installed the Storefront theme."

This is my style.css content:

/*
 Theme Name:     Storefront Child Theme
 Theme URI:      http://docs.woocommerce.com/document/storefront/?_ga=2.117121861.2123701926.1501626121-661578052.1501626121
 Description:    Storefront Child Theme
 Author:         Woocommerce
 Author URI:     http://www.woothemes.com
 Template:       Storefront
 Version:        2.2.4
*/
 
@import url("../storefront/style.css");

How to resolve this?
Thank you
