Dear all,  
When I compile

```julia
using Plots
import Contour: contours, levels, level, lines, coordinates
f(x,y) = 2 - (x^2 + y^2)
xs = range(-5, stop=5, length=100)
ys = range(-5, stop=5, length=100)
zs = [f(x,y) for y in ys, x in xs]
gr()
contour(xs, ys, zs, levels = [-1.0, 0.0, 1.0])

```

a big error message apperars and Julia restart. See:

```julia

Have you tried the suggestion from  
[https://github.com/jheinen/GR.jl/issues/122](https://github.com/jheinen/GR.jl/issues/122)  
which is

```julia
Pkg.update("GR")
Pkg.update("Plots")
ENV["GRDIR"]=""
Pkg.build("GR")

```

Nothing yet. I have executed the codes:

```julia
Pkg.update("GR")
Pkg.update("Plots")
ENV["GRDIR"]=""
Pkg.build("GR")

```

(as you can see in the next print)

 ![print1](https://global.discourse-cdn.com/julialang/original/3X/9/b/9bc41e72de7e9f0abac89fa16504c4630d2f99b9.png)

But when I compile:

```julia
using Plots
gr()
f(x,y) = 2 - (x^2 + y^2)
xs = range(-5, stop=5, length=100)
ys = range(-5, stop=5, length=100)
zs = [f(x,y) for y in ys, x in xs]
contour(xs, ys, zs,level=[1,2])

```

nothing works. Its terrible. See below:

Could anyone can help me please?

Have you tried this with standard Julia (not JuliaPro) ?

There is difference?

If I was using JuliaPro, I would probably send in a support ticket to JuliaComputing. That may be the best route for some users. If I was seeking help from this community forum, I might want to give the community edition a try if everything else is failing just in case. I just use Julia, not JuliaPro so I cannot be sure about the difference.

Could you try to narrow down which line of code produces the error? Is it the call to `contour` or is it `gr()` as the title implies?

It is also possible that the issue is actually Juno, the editor, so it may be good to try with Julia outside of Juno.

Could you post the contents of `C:\Users\Usuário\.julia\packages\GR\RlE5y\deps\build.log` and confirm the existence of `C:\Users\Usuário\.julia\packages\GR\RlE5Y\src\..\deps\gr\FONTS\GKSFONT.DAT`?

I’ll ping GR author @jheinen in case he can help here.

By the way, I’m not sure exactly what you are doing with the Contour package, but this code works for me:

```julia
using Plots
f(x,y) = 2 - (x^2 + y^2)
# You might want to consider `length = 101` or `-5:0.1:5`
xs = range(-5, stop=5, length=100)
ys = range(-5, stop=5, length=100)
zs = [f(x,y) for y in ys, x in xs]
gr()
contour(xs, ys, zs, levels = [-1.0, 0.0, 1.0])

```

Older version of `Plots` may not export `contour`, but this is not your problem at the moment.

It might be useful to at least reference your previous post:

Afer inumerous attempts, the error changes. At least after compiling `gr()` the core is not reset. the error is this:

```julia
using Plots
gr()
x=0:0.01:2*π
y=sin.(x)
plot(x,y)

```

```julia

Hi. I have the same issue ‘GKS: file open error’. I just installed Julia 1.6.3, 64 bit, on Win 10.

I see that OP’s windows user profile is Usuário in ‘C:\Users\Usuário\ .julia’. My profile is ‘Bärbara’, that is 'C:\Users\Bärbara\ .julia'.

‘using Plots; gr()’ works fine on my other computer, where I also just installed Julia.

Perhaps the issue is with the somewhat unusual letters?
