After some problem with Julia vs. Python in Jypyter notebooks, I’m removing every trace of Python and Julia on my computers, and re-installing first Julia v. 1.2.0 with packages, and then Anaconda. [I mainly use Julia, but occationally need to run some Python code.]
Reinstalling Julia with packages worked fine on my desktop, and previous problem with IJulia was solved. Next, I’m trying to cleanse and reinstall Julia on my laptop. On my laptop, `Plots` doesn’t compile, and complains about a missing `ffmpeg`.
Anyone knows what this can be?

Can you run `]build FFMPEG` ?

I found `FFMPEG.jl`, and tried to `Pkg.add("FFMPEG")`. This worked, and now I could do `using Plots` without error message. When I tried to specify `pycall()`, I was told that I needed to `build PyCall`. I’m in the process of doing that now.

OK… seems to have worked – `build PyCall` caused the installation of a load of Python code.
Hm… I used exactly the same \*.jl script of adding packages on my desktop and on my laptop. My laptop must have had a hiccup … seems like:
1. Adding `ffmpeg` and
2. Building `PyCall`
solved the problem. The only “real” difference regarding graphics between my desktop and my laptop is that my laptop has an NVIDIA 1050 graphics card, but I would be surprised if that should have caused the problem…

While I’m at IJulia… if anyone has an idea why sometimes, plots are embedded in a scrollable window,
while other times, they appear without such scroll bars:
I’m curious to know… it seems to be random. Of course, if the plot is “tall” or “wide”, I could see why this happes, but it seems to happen randomly for plots of the same size…
