Running plot(1:5) caused an error after doing the following installation steps…

1. Installed Julia 1.0.0
2. Installed Python( [Anaconda | Anaconda Distribution](https://www.anaconda.com/download/#windows) )
3. Run Anaconda as admin  
4.Installed matplotlib ( conda install -c conda-forge matplotlib )
4. Install plotting:  
ENV[“PYTHON”]=“c:\Users\ME\Anaconda3\python.exe”

]  
build PyCall  
build PyPlot  
backspace

1. Quick test:  
using PyPlot  
plot(1:5)

…which gets this error:
