How to manage Unfold precompiling error: _iszero not defined?

Question

On a new computer I was trying to run Unfold and UnfoldMakie. See this error in both cases. Like something wrong with the MutableArithmetics library. Any idea how to manage it?

Also get this after update of MakieCore package:

Versions:

• Julia 1.8.0.
• Unfold v0.3.11
• UnfoldMakie v0.1.4

Answer 1

Finally figured out the problem:

First, I created a new environment/project. https://pkgdocs.julialang.org/v1/environments/

Second, activated it in the notebook. Third, installed problematic libraries through this code:

import Pkg
p = "Unfold"
Pkg.add(p)
Pkg.build(p)

Answer 2

It seems as a solution:

These packages work in the julia envv1.7, but do not work in v1.8.

In VScode you can change it here:
