Error precompling HomotopyContinuation

[Seth-Kurankyi]

I get an error trying to load HomotopyContinuation. I'm not sure how to fix it. The error message is shown below:

The issue seems to be that Arlib didn’t install properly. What happens if you add it explicitly

using Pkg
pkg"add Arblib"
pkg"build Arblib"

after this you should be able to do using Arblib and using HomotopyContinuation

Thanks @saschatimme The error gets fixed after just updating the package registry Pkg.update()

Great 😊
