Julia can't precompile various packages

[fuzzy]

Hey,

I’m a relatively new Julia user, though I have run some small scripts in the past. I am currently encountering an error when Julia tries to precompile a few different packages that I need. The error is extremely long and I can’t parse it, so all I can do is reproduce it below:

ERROR: LoadError: LoadError: InitError: could not load library "C:\Users\YOTAM\.julia\artifacts\3aff78028a0bb2ad40ebc3ae7e465a52dcbe2730\bin\libcairo-2.dll"

(This particular error occurs when I try to load a package called “Laplacians”).

Any ideas? I should add that my OS is Windows 10.

Putting your error in code blocks makes it a little easier for us to work out, see here:

Please read: make it easier to help you

Welcome to the Julia Discourse! We are enthusiastic about helping Julia programmers, both beginner and experienced. This public service announcement (PSA) outlines best practices when asking for help. Following these points makes it easier for us to help you and more likely you’ll get a prompt, useful answer. Keywords are highlighted to make it easier to refer to specific points. Choose a descriptive title that captures the key part of your question, eg “plots with multiple axes” instead of …

But you it seems that something is wrong with Cairo_dll install, and maybe your environment generally? You can maybe try ] update first.

[fuzzy]

Thanks,

tried “] update” and got that the packages FFMPEG_jll, PyCall, GR_jll, Plots failed, and got the same long error message in response to “using Laplacians”.

[ufechner7]

Can you try to install the package Laplacians in a separate project:

mkdir myproject
cd myproject
julia --project="."

and then in Julia:

using Pkg
Pkg.add("Laplacians")

Does that work?

[fuzzy]

Thanks,

Unfortunately no, in this case I get that the following dependencies errored’‘’

✗ libass_jll

Working perfect for me using Julia 1.8.2 on Windows 10. What is the output of

pkg> st

You can enter the package manager mode with the ] key and get back the Julia
prompt with the backspace key.

[fuzzy]

The output is

  Status `C:\Users\YOTAM\myproject\Project.toml`

Should I try to switch to 1.8.2?

OK, I get a test failure:

Not sure if this is different than test. FWIW I have been able to use this package using Google Colab.

[ufechner7]

I was running:

pkg> test Laplacians

using Julia 1.8.2 on Windows 10, and the tests passed.

So please try to use Julia 1.8.2…

And if you want to learn how to make sure that old package versions keep working read: Working with Julia projects | Julia programming notes

By the way, the long term stable release is 1.6.7. If the package does not work with this version you could create a bug report at Issues · danspielman/Laplacians.jl · GitHub …

[ufechner7]

On the other hand, you can see here: Laplacians.jl/Project.toml at master · danspielman/Laplacians.jl · GitHub that the oldest version of Julia that is supported by the current version of Laplacians is 1.7.0…

Can you check if this file exists on your computer:

It exists on my computer.

Nope, I’m getting

The system cannot find the path specified.

[ufechner7]

Does this path exist:

C:\Users\YOTAM\.julia\artifacts\3aff78028a0bb2ad40ebc3ae7e465a52dcbe2730

or this one:

[fuzzy]

Yes, both paths exist.
