I have just installed Juno and I have a problem with installing the package PowerModels. I’m using windows 10 home 64-bit.  
The problem is displayed in the next lines

This was resolved in this thread, [Problem with installation · Issue #711 · lanl-ansi/PowerModels.jl · GitHub](https://github.com/lanl-ansi/PowerModels.jl/issues/711)

The root cause seemed to be a windows configuration issue.
