Error: Unable to resolve module poly-decomp from node_modules\matter-js\build\matter.js: poly-decomp could not be found within the project.

Help me ! I don't run project FlappyBird

Possibly related to #559?

Can you give more information?

• Can you confirm you have installed the dependency in the project e.g. npm install poly-decomp --save?
• What was the last working version of matter-js for this?
• What environment? npm / node version?
• Can you share an example or project link?

Same thing here. Installing the dependency manually as you suggest @liabru is a good workaround.
Issue occurs with a simple import { Engine } from "matter-js", in webpack with matter v0.16.0

[liabru]

@entozoon thanks for confirming. That's not a workaround though, that's the intended approach.

I guess it should be made clearer in the docs! That said, I am hoping to be taking this out of the core project when I get around to it.

[entozoon]

Fair enough @liabru ! :)

[liabru]

@entozoon Actually, are you saying you get an error even when not using Bodies.fromVertices?

This might be a webpack specific problem in that case, as I've tested this in straight node.js without seeing that.
What version of webpack? Could you share the config?

[nnhjs]

Thank you, i will install npm install poly-decomp --save .
Last, i install matter-js !

[entozoon]

@liabru No buddy; installing poly-decomp fixed everything. Just needs adding to the readme and/or the error output.
I probably wouldn't have closed the issue until then @nnhunguet as it'll keep happening for people

[liabru]

Thanks for confirming all, I will be looking at improving the docs and error outputs on this.

Just to check in case of a regression, @nnhunguet was this working before upgrading?

If so, how was it working? Using a global decomp?
