Hm, that's interesting, thanks for reporting this!

It looks like we're missing an upper bound on compatibility with Rotations.jl. I may just need to create a new release; let me see...

I just tried adding MeshCat in a new package environment, and I cannot reproduce this error. Do you maybe have Rotations.jl pinned to an old version? What does pkg> status show?

[baggepinnen]

Rotations is on v1.0.1 in pkg> st -m . I just tried using MeshCat again and it worked, so I have somehow managed to modify my package environment since I reported the issue and I can no longer reproduce it either :/

Ok, no worries. Feel free to re-open this if it happens again.
