Problem with installing a child theme from third-party Alpaca theme
I'm new in Magento world and have a little problem with I can't manage with. I want to work on third-party open source Magento theme called alpaca and customize components but I have problem with installing a child theme from alpaca parent. I've followed with official documentation from theme's creators but this one isn't written in clarify way and hard to understand for some newbie like I am. The documentation is here
Everything I do is alright until I try to deploy project and compile child theme. When i type:
bin/magento setup:static-content:deploy -f
I get the red wall with errors telling that:
for many files. Except that, in some moment i get error: "unable to load theme by specified key" somewhere in red block.
When I type:
is get some error too during Module 'Magento_Theme' execution that says: My guess is that I'm doing some mistake with theme configuration files like composer.json, themes.xml etc. mentioned in alpaca docs or something else but can't realize what is wrong. I tried everything including clearaing/flushing cache, changing datebase keys associated with themes that cold be a potential cause, removing empty files, removing, var, pub, di catalogs and some others potential solves but nothing helped. As a docs says, I setted up own repositories for this alpaca theme and install those with composer require. It went properly.
I think these files are most important relation to documantation. I asked creators for help on github issue but noone reposnded to me. If you want additional info about my config etc. I can give wherever you need to diagnose the problem.
