Cannot Install CuClarabel in Julia

[jiachangliu]

Hello,

Thanks for developing this package! I tried installing CuClarabel by using the command suggested in the README:

pkg> dev https://github.com/cvxgrp/CuClarabel.git

However, I met with the following error message:

ERROR: Unsatisfiable requirements detected for package HSL [34c5aeac]:
 HSL [34c5aeac] log:
 ├─possible versions are: 0.1.0-0.3.6 or uninstalled
 └─restricted to versions 0.4 by Clarabel [61c947e1] — no versions left
   └─Clarabel [61c947e1] log:
     ├─possible versions are: 0.9.0 or uninstalled
     └─Clarabel [61c947e1] is fixed to version 0.9.0

What should I do to resolve this message? My Julia version is 1.10.4.

Thanks!

It's claiming that HSL is only available in version 0.1.0-0.3.6, but Clarabel wants 0.4. I don't really understand why that's happening, but the current version of HSL is v0.5 on juliahub.

HSL isn't actually necessary for Clarabel to work since it is a package that provides an optional solver interface. It might work if you just delete that dependency from the Clarabel.jl Project.toml file, but you shouldn't really need to do that.

What happens if you just add the HSL package directly via the package manager?
