Hi, I am moving all of my developments from windows to Linux because Linux is just more convenient. I am using WSL. _Version information can be found below._

**I installed maxima first before running using Maxima.jl**  
`sudo apt install maxima`

I checked that the bash accepts `maxima` and I was able to enter maxima terminal from bash.  
I also tried `julia> run(`maxima`)` and I was able to enter the maxima terminal as well.

I then installed Maxima.jl with `Pkg.add("Maxima")` and ran `using Maxima` in the julia terminal, and this is the output:  
`julia> using Maxima`  
`[Info: Precompiling Maxima [e6386f5f-9a8a-5a5d-a605-d2d61207ca5a]`  
`WARNING: could not import Base.expand into Maxima`

The julia terminal was stuck here for hours and the windows task manager shows 0% cpu usage for the _julia_ process. I ended up interrupting it by doing _CTRL+C_ because it clearly wasn’t going anywhere. If I try to run `using Maxima` again, the julia terminal gets stuck indefinitely again.

This is the output when I interrupt it:

**I am not sure what I am doing wrong, is there a fix for this?**
