MAC Plots.jl warning and testing errors

[GravityAssisted]

Hi I am trying to install GLVisualize on mac and I keep on getting this warning and then errors:

WARNING: Plots.jl is not installed, excluding a lot of interesting examples from the tests
and a nice summary.
Please consider doing: `Pkg.add("Plots"); Pkg.checkout("Plots", "dev")`

ERROR: LoadError: LoadError: LoadError: Unable to load

BTW: I have Plots.jl already installed.

[SimonDanisch]

That's just a warning! The real error is, that ImageMagick isn't build correctly..
Please re-run Pkg.build("ImageMagick")... And maybe update it!

[GravityAssisted]

Thanks @SimonDanisch . After running the following commands to fix ImageMagick and then reinstalling GLVisualize, it seems to work. I am still getting the Plots.jl warning, even though I have Plots already installed.

brew = Pkg.dir("Homebrew", "deps", "usr", "bin", "brew")
run(`$brew remove imagemagick@6`)
run(`$brew prune`)
Pkg.build("ImageMagick")

[SimonDanisch]

Uh, for some reason it seems I've disabled the Plot detection:
https://github.com/JuliaGL/GLVisualize.jl/blob/master/examples/ExampleRunner.jl#L22
Let me try out, if the plots backend is functional right now

[mkborregaard]

It isn't right now #175
