Most times if you restart Julia and use (using ...) the package, the precompilation will finish its job and the package will work. Sometimes what happens is that some packages cannot be compiled in the current section because other packages are already using them as dependencies (something like that), but starting a fresh Julia section does the trick.

Thanks, it worked!

So does that mean those packages with a ? before them in my initial post were being used as dependencies by other packages at that time?

But when I am trying to run a module with AbstractPlotting in it, I get this Error:

ERROR: LoadError: UndefVarError: AbstractPlotting not defined

using AbstractPlotting.Colors
AbstractPlotting.inline!(true)

So the error comes from the second line. When I am commenting it, the code runs. What is it about the .inline!(true) part that seems to go sideways?

Seems that you imported only the Colors package from within AbstractPlotting. Use only:

using AbstractPlotting

(I do not have that package installed, but that might be it)

Oh, thank you again :man_facepalming:
