Dependencies not compatible with Nodejs 15 and above

Hey, I tried to install the project dependencies with yarn as described in the Readme.md but received the following error:

Googling around revealed that this has to do with incompatible nodejs to package version.

I performed some tests with different Nodejs versions and found out, that it breaks beginning with Nodejs 15, versions below 15 work and can be build and used like described in the Readme, above and including 15 do not work. Maybe you would want to update your dependencies to work with an up-to-date Nodejs or maybe at least hint towards this problem in the Readme.md file to save people the time it takes to debug and find the cause.

Best, Nico

Oh yeah, I noticed that before. It's because of node-sass. I'll try fixing it again, it's just used by webpack for the visual test app I included.

[MatthewDorner]

OK, I removed node-sass and updated the other dependencies, should work better now.

Cool, thank you!
