I managed to install in julia 1.5.4 CoolProp.jl:

```julia

    Cloning git-repo `C:\Users\hermesr\Documents\GitHub\CoolProp.jl`

(@v1.5) pkg> build CoolProp

```

But in Julia 1.6.0 I get this error alert:

```julia

```

How to process? What am I doing wrong?

This looks like the same issue you have in [Julia 1.6.0 add Package OhMyREPL](https://discourse.julialang.org/t/julia-1-6-0-add-package-ohmyrepl/58148).
