`using Plots` errors (`ERROR: LoadError: InitError: UndefVarError: `GR_jll` not defined`)

Did you try these specific instructions that I posted yesterday?

GR_jll not compiling in Julia 1.10.3

Here’s workaround until the registry changes propagate. This includes force precompilation of GR. using Pkg # skip activation of a temp environment if you are trying to fix your environment Pkg.activate(; temp=true) # Add LERC_jll version 3 Pkg.add([ PackageSpec(name="GR"), PackageSpec(name="LERC_jll", version="3") ]) # Force GR to precompile Base.compilecache(Base.PkgId(Base.UUID("28b8d3ca-fb5f-59d9-8090-bfdbd6d07a71"), "GR"))

using Pkg
# skip activation of a temp environment if you are trying to fix your environment
Pkg.activate(; temp=true)
# Add LERC_jll version 3
Pkg.add([
    PackageSpec(name="GR"),
    PackageSpec(name="LERC_jll", version="3")
])
# Force GR to precompile
Base.compilecache(Base.PkgId(Base.UUID("28b8d3ca-fb5f-59d9-8090-bfdbd6d07a71"), "GR"))

There was package, LERC_jll which contained a binary neeed by libtiff which is need by GR which is needed by plots. A few days ago that library was updated to version 4 form version 3. It turns out libtiff is not compatible with version 4 which started the failure cascade.

I should also mention that perhaps Plots.jl should not be the first plotting package you reach for, although I understand why that might seem like the most obvious choice. As you can see above it has a a lot of external dependencies.

I generally reach for Makie.jl first, specifically the GLMakie.jl backend.
