Woocommerce SKU Generator WP plugin

I attempted to install the Woocommerce SKU Generator WP plugin and I followed their instructions.
"Upload the entire 'woocommerce-product-sku-generator' folder to the '/wp-content/plugins/' directory"

And then when I attempted to activate, I got this error:

Fatal error: Call to undefined function wc_enqueue_js() in /homepages/41/d370157330/htdocs/liberaleffects/wp-content/plugins/woocommerce-product-sku-generator/woocommerce-product-sku-generator.php on line 84

Any suggestions on how to repair this would be very helpful.
