It looks like you've `dev`ed an older version of MechanismGeometries (`v0.1.2+`), as well as the latest version of `MeshCat` (`v0.6.0`). The latest version of MeshCatMechanisms requires at least `v0.2.0` of...

`pkg> up`? Also be sure to `add MeshCatMechanisms` instead of `add https://github.com/JuliaRobotics/MeshCatMechanisms.jl`.

I see in https://github.com/rdeits/MeshCat.jl/issues/95#issuecomment-472453005 for MeshCat: `possible versions are: [0.0.1-0.0.3, 0.1.0-0.1.2, 0.2.0-0.2.3, 0.3.0, 0.4.0, 0.5.0] or uninstalled` and MeshCatMechanisms: `possible versions are: [0.0.1-0.0.6, 0.1.0-0.1.1, 0.2.0-0.2.1] or uninstalled`. Version 0.6.0 of...

Yes. I'm not 100 percent sure, but I think that the JuliaPro package registry is a snapshot of the general package registry that is only updated with each release. That...

Yeah, I've gone back and forth on this myself. Actually, StaticArrays is in a similar position now with `LinearAlgebra`, see also https://github.com/JuliaArrays/StaticArrays.jl/pull/464 for some discussion. I'm not sure what the...

Thanks, Chris, that'll make it easy to fix on this end. FWIW, removing the `Manifest.toml` in my `dev`ed RigidBodySim and `instantiate`ing works fine; probably a compatibility issue with Atom via...

@sn3akyLynx, are you also using Juno?

I personally think that Juno's design decision of installing its packages next to the user's packages is very unfortunate, as it can lead to these kinds of situations (I've complained...

@ChrisRackauckas, it turns out that the `PeriodicController` issue is due to the fact that callbacks passed into the `ODEProblem` constructor and those passed into `solve` are no longer merged into...

Thanks. Although it conceptually makes sense to me to handle all keyword arguments the same, I think that having the problem's keyword arguments be silently overwritten by the `solve` keyword...
