I've created my own custom theme and uploaded it to my private package repository. This works fine and downloads my folder into vendor/<vendor>/theme-my-theme I run:

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy

My theme doesn't list itself in setup:static-content:deploy or in the admin panel. I then install snowdog/theme-blank-sass and this shows up fine.

Any ideas as to how to get Magento to register my theme? Please note that this theme was developed in app/design/frontend and worked fine.

I've found the cause of the problem. In Composer's installed.json file my theme declaration is missing the autoload section (as well as description). This means that Composers autoload_files.php isn't getting updated with my autload file registration.php. Anyone know more about this or how to fix it?

  • First of all, Welcome to Magento Stack. Did set your theme in Magento2 Admin ? – Abhishek Panchal Aug 18 '17 at 14:41
  • Thanks for the welcome. :) It doesn't show up in magento 2 admin but the snowdog/theme-blank-sass does. I can't see any differences (aside from my necessary configs) in the important files between the theme on packgist vs my custom theme from private repo – Max Atkins Aug 18 '17 at 14:44
  • Can you please update your Question with your code. How you created your custom theme? – Abhishek Panchal Aug 18 '17 at 14:46
  • @AbhishekPanchal done now – Max Atkins Aug 18 '17 at 14:52
  • Please make sure all file name should be in small letters. Also version shouldn't be ''dev-master'. Please check below link to create custom theme. devdocs.magento.com/guides/v2.1/frontend-dev-guide/themes/… – Abhishek Panchal Aug 18 '17 at 14:59
