I am trying to install a required package but it doenst work and I am getting a bunch of question marks. How do I solve this? Thank you.

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:

```julia

```julia
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)
