Pyplot.jl is a backend for PrettyPlots.jl and it requires a newer version of matplotlib or this error can pop up

First attempt to fix did not work, which was

ENV["PYTHON"]=""
Pkg.build("PyCall")
huckl3b3rry87 commented 5 years ago

Also in the terminal type

conda install matplotlib

Instructions installing conda

huckl3b3rry87 commented 5 years ago

if conda downgrades matplotlib 

conda install matplotlib=2.2.3
huckl3b3rry87 commented 5 years ago

Given that we are using conda now, try building PyCall with it as

ENV["PYTHON"]= "/home/febbo/miniconda2/bin/"
"/home/febbo/miniconda2/bin/"
julia> Pkg.build("PyCall")

These python path issues need to be considered together https://github.com/JuliaMPC/MichiganAutonomousVehicles.jl/issues/8
