I got such output after istlalling DifferentialEquations.jl package:
“”"
Precompiling project…
✗ OrdinaryDiffEqRosenbrock
✗ OrdinaryDiffEqDefault
✗ OrdinaryDiffEq

✗ DifferentialEquations
31 dependencies successfully precompiled in 92 seconds. 612 already precompiled.
5 dependencies errored.
For a report of the errors see julia> err. To retry use pkg> precompile “”"
And i don’t know why, don’t know how to fix it. Generaly status shows that packages is istanlled, but proble those sub-packages not.
I will mention that i installed julia with juliaup.
The err return (in short) this:
‘’’ PkgPrecompileError: The following 1 direct dependency failed to precompile:

We had a hiccup today in the release process. It got fixed. You should be fine if you try again (after updating your registry)

Hello, I am getting the error now.

Stacktrace:

I tried deleting ~/.julia/compiled/v1.11/ and then running :
Pkg.Registry.update(); Pkg.update(); . What should I try next?

What else is in your Project.toml that could be holding stuff back? This was handled quite awhile ago but there may be some funky lower bound

Please share the output of:

using Pkg
Pkg.status()

This is the output

I created an empty folder, added your Project.toml file, and instantiated your project.

Then I added DifferentialEquations.jl . All works fine without error:

Thanks for checking :D, so it definitely is on my side, I am also on linux. I think I have just something setup incorrectly, I may not be launching my code from correct environment. I am looking into it right now. I am new to Julia, so I will take a closer look into how projects and environments work.

Have a look:

But sometimes also files in ~/.julia/compiled or other subfolders of ~/.julia get corrupted. You can safely delete the ~/.julia/compiled folder if you have the time for re-compiling everything.

If you open a folder or a project in VSCode it asks you if you want to activate the new environment, just say “YES”. You can also change the environment in VSCode by clicking on “Julia env” in the status line:
image

Finally, in VSCode I always just launch the bash terminal, and start Julia using

julia --project
