Prestashop wishlist module cannot be install and configure

[Jasper Jee]

Problem when installing the wishlist module in Prestashop ver. 1.7.7.8 the module is from https://github.com/PrestaShop/blockwishlist

Download the zip file and extract and change the filename to without "-dev" Zip it again and upload via Prestashop

Here's the error shown

Attempted to load class "Install" from namespace "PrestaShop\Module\BlockWishList\Database".
 Did you forget a "use" statement for e.g. "PrestaShopBundle\Install\Install", 
"PrestaShop\AccountsAuth\Installer\Install", "PrestaShop\Module\PsAccounts\Module\Install" 
or "PrestaShop\Module\PsEventbus\Module\Install"?

[Symfony\Component\Debug\Exception\ClassNotFoundException 0]

 

After I move the Install class and uninstall class to under blockwishlist.php, the installation can be processed, but another problem shows on. When I try to enter the module configure page, the error pop up...

The controller for URI "/modules/blockwishlist/configuration" is not callable. 
Class "PrestaShop\Module\BlockWishList\Controller\WishlistConfigurationAdminController" does not exist.

[InvalidArgumentException 0]

 

 

I've tried to clear the var/cache but still..

Can anyone help on this? Thx in advance!

PHP ver. 7.3.2
