Not working for me

[craftercis]

Hey,

Sorry but this is not working for me. I installed all the requirements and followed the steps listed. But when I click on preview theme in WP this is the error I get:

Sage › Error
Autoloader not found.
You must run composer install from the Sage directory.

Can you help me with this?

These are problems that i'm getting when create a new theme with your command. Is that the problem? And how should I fix that? Sorry I'm pretty new with this stuff :)

Okay. Its now kinda working. I fired this command:
composer install --ignore-platform-reqs

in the theme folder. I activated the react script but there are no graphics. Only a button and text. When you create a standard vite/react app there are also logo's with animations. Is there anything I'm doing wrong?
