Package version conflict with MeshCatMechanisms

#1

After my daily ]up today, I am suddenly getting a number of: ERROR: Unsatisfiable requirements detected for package messages.

This started with MeshCatMechanisms and RigidBodySim, so I removed them along with MeshCat and MeshCatGoemetries, which seemed to be implicated. Typed resolve and then ]up and it’s OK. Reinstalling gave the original problem (pasted below).

Reading similar posts led me to suppose that the Registry might be corrupt, so I removed the ~/.julia/registries/General folder followed by an ]up but no improvement except that now TexExtensions added itself to the list of unsatisfiable requirements. This was caused by SIUnits. Removed that package and any other packages (including the above) that might be in anyway related. Did resolve (see below), up – everything is fine, tried to reinstall said packages but still the same.

All I can think of now is deleting everything related to Julia, including the .julia directory. But before I do, has anyone had similar problems today? Or is this just me?

I was just able to add MeshCat successfully. What else do you have in your environment?

MeshCat is no problem for me either – it’s MeshCatMechanisms that doesn’t install.

I have a huge amount in my environment!! I’ll try doing gc to see what happens …

Only 444 packages deleted!!

MeshCat and MeshCatMechanisms both install just fine. It seems like something else in your environment has conflicting version requirements with one of them. The current version resolver is unfortunately not very helpful with telling you what the problem is. I would try getting rid of packages that you don’t need.

OK, will do, many thanks!

Your MechanismGeometries reports that it is restricted to version 0.1.2, which is too old for the latest MeshCatMechanisms. Can you try pkg> free MechanismGeometries ?

Probably would have worked but in the mean time I took the more draconian action of deleting .julia/.. and everything is fine except for my own packages! :slight_smile: Problem now gone away!

Thank you.

Edit: Obviously reinstalling everything I need, which actually is a lot!
