Problem with Julia installation on Win 10

New to Julia
1

Hi,
I’m a relatively new Julia user trying to install Julia + PyPlot on a new computer running Windows 10. I have only used Julia on unix before and had no problems.

After running the Julia installer, which works fine, I try to add PyPlot but it fails. I tried the recommended installation procedure from the beginning several times without luck.
The problem seems to be with the minconda package.

Any help is much appreciated.

This is what the Julia session looks like after a fresh installation trying to add PyPlot:

The error message says:

have you tried running Pkg.add("PyPlot") and/or Pkg.build("PyPlot") again?

Hello @jmo I also use Julia on Windows 10.
Pkg.add(“PyPlot”) Works oK for me.
As rdeits says - please try this again. If you still are having problems, then replya gain to this topic.

@rdeits I tried running Pkg.add(“PyPlot”) and/or Pkg.build(“PyPlot”) multiple times and I also reinstalled Julia from the beginning several times without success.

Since the problem appear to be related to the miniconda package not being able to download I installed Anaconda. And after finishing the Anaconda installation including a test that matplotlib was working in python I pointed julia to it.

julia> ENV["PYTHON"]="C:\\ProgramData\\Anaconda2\\python.exe"
"C:\\ProgramData\\Anaconda2\\python.exe"

julia> Pkg.build("PyCall")

julia> using PyPlot

julia> plot(1:10)

Now I got one step further and PyPlot seems to install ok. However, in the last step when i run a test plot(1:10) windows gives me: “Runtime error! Program C:\Users\odj\Appdata\Local\Julia-0.6.2\bin\julia.exe
R6034 An application has made an attempt to load the C runtime library incorrectly. Please contact the application’s support team for more information.” and hangs Julia.
