loadODESolvers() not working

I am using Windows 10 64 bit.
I performed the following steps in Juno in Julia REPL:
] add ODEInterface
build ODEInterface

The ODEInterface package is added and built as normal however the loadODESolver() command throws an “UndefVarError”.
I have installed and added mingw64 to my path so cannot understand what is going wrong. And I cannot use any of the ODEInterface functions like radau in my code. Please help.

This is worth asking directly as an issue in ODEInterface.jl

Thanks for the suggestion.
You mean the GitHub repository for ODEInterface?

Yes. I do not think the author of that package checks the Discourse very often.
