Plots and GR_jll is not working and fails to precompile

New to Julia

Hello

I am trying to use julia for my Linear Algebra and Multivariable Calculus courses that requires plotting, however I cannot seem to get the package to work. I have read all the other plotting post as well as stack overflow and other place, but I cannot seem to find a solution. I have updated packages and registers, built, removed, reinstalled, installed with other packages, precompiled packages and many other things but I cannot get it to work. Please can someone help. Your assistance would be greatly appreciated. Please see below program code and the error messages on my machine.

PROGRAM CODE: -------------

import Pkg;

Pkg.add(“Plots”);

using Plots;

f(x) = sin(x);

plot(f,0,2*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

g(x) = cos(x);

list of two functions f and g included in the plot

plot([f,g],0,2*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

savefig(“firstgraph.pdf”);

Could you try the following code and report any output?

using Pkg
pkg"add GR_jll"
using GR_jll
Pkg.status()

Hello

It did not work. Please see below.

CODE
I updated the code as follows:

"import Pkg;

Pkg.add(“Plots”);

Pkg.add(“GR_jll”);

using GR_jll;

using Plots;

Pkg.status()

f(x) = sin(x);

plot(f,0,2*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

g(x) = cos(x);

list of two functions f and g included in the plot

plot([f,g],0,2*pi,title=“First Graph”,xlabe = “x”, ylabel = “y”);

savefig(“firstgraph.pdf”);"

Probably a failed download.

Delete C:\Users\Tshepho.julia\artifacts\c3712e14d6f387fa0a6d1509acbdd4b8976e87d1 manually, then run using Pkg; pkg"instantiate", it should download the failing artifact again.

Try the solution I found here:

Basically, execute the following and then restart Julia:

Base.compilecache(Base.identify_package("GR"))
