Unable to install from wpackagist using composer

Hi everyone.

I’m developing a website where I’m trying to use composer to manage my dependencies.

The theme I’m using, which I bought from Envato, did install correctly using composer. It requires some plugins, such as Contact Form 7 which installed correctly.

I changed my minimum-stability requirement to “dev” and added the “prefer-stable” clause but the package keeps not being found and trying to install it results in the following message:

lando composer require "wpackagist-plugin/custom-fonts"

I also tried:

lando composer require "wpackagist-plugin/custom-fonts:@dev"

How can I install Custom Fonts using composer?

It does show correctly in wpackagist: https://wpackagist.org/search?q=custom-fonts

Thanks!
