BilevelJuMP is restricted to v0.5.2 on windows while is installed normally to v0.6.2 on linux

[wj-qiao]

When trying to install BilevelJuMP on Windows, it's limited to version 0.5.2, and it shows that updates are available, but I cannot update to version 0.6.2. However, on the Linux platform, I can install version 0.6.2. I'm not sure where the issue is coming from.

What is the output if you do ] add [email protected] in the package manager?

The last CI job installed and passed tests with 0.6.2 on Windows: https://github.com/joaquimg/BilevelJuMP.jl/actions/runs/5913458217/job/16037874116

So you likely have a different package that is holding you back.

It gives me the following log, is there a package installation that's causing version conflicts?

The problem appears to be https://github.com/chkwon/TrafficAssignment.jl.

If you remove it, you should be able to install a newer version of BIlevelJuMP.

Note that https://github.com/chkwon/TrafficAssignment.jl hasn't been updated for a couple of years.

[wj-qiao]

yes, after removing it, the latest version of BilvelJuMP is installed.
Thank you @odow
