Issues on using Plots package in Julia

Question

I'm trying to use Plots package in Julia but I get an error message I don't fully understand. Using a Jupyter notebook I followed the canonic way to install and use the package with:

Pkg.add("Plots")
using Plots

But after then I got this error message:

INFO: Precompiling module Plots.
WARNING: Module Compat with uuid 131681569370755 is missing from the cache.
This may mean module Compat does not support precompilation but is imported by a module that does.
ERROR: LoadError: Declaring __precompile__(false) is not allowed in files that are being precompiled.

Could somebody please help me to understand this error and what can I do to fix it? Any help will be much appreciated.

You can see in the first line here that Compat definitely does support precompilation, so first try Pkg.rm("Compat") ; Pkg.update() ; Pkg.add("Compat"). Also probably worth adding the output of Pkg.status() to the question. — Colin T Bowers

That's because you already had Compat in your scope before trying to update. It then has an issue of trying to precompile using a new version of Compat while an old one is still in scope. To fix this, just restart Julia and do using Plots.
