> Hello,
>  
> I am running Julia 1.4.2 in Jupyter Notebook on a Windows 10 machine.
> I have installed Julia’s GLPK.jl package. When I run the code `using
> GLPK`, I get the following error message:
>  
> ERROR: LoadError: ArgumentError: Package GLPK does not have CEnum in
> its dependencies:
> - If you have GLPK checked out for development and have
>   added CEnum as a dependency but haven't updated your primary
>   environment's manifest file, try `Pkg.resolve()`.
> - Otherwise you may need to report an issue with GLPK
>  
> As suggested in the message, I am reporting the error.
> `Pkg.resolve()` did nothing, nor am I aware of checking out GLPK for
> development; this is my first time using the solver.
>  
> Any help would be much appreciated.
