I need help with this problem


Note: the gsap object exist, so the import works


"gsap": "3.11.2"

Code: I use js modules without any framework, just native js

Unless you're a very advanced user who doesn't need any CSS animating functionality, you should NOT be importing the "gsap-core" file from the raw src directory. That doesn't include CSSPlugin. Again, it's only intended for very advanced users who have particular needs (no use for CSS animating) - that's almost nobody. :)


Typically you don't have to write out the whole path like that anyway - just use the default like: 

import gsap from "gsap";
import ScrollTrigger from "gsap/ScrollTrigger";

If you really want to write out the whole path, then use the index.js file, not gsap-core.js.

Thanks, the problem was not import index.js


But I had to import the complete path, in this way works fine.

That's highly unusual. Maybe you've got an odd build system setup that doesn't work with the typical npm/yarn package manager, but I'm glad you got it working. 👍
