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:

```julia

```

(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:

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

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”.

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

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

```

and then in Julia:

```julia
using Pkg
Pkg.add("Laplacians")

```

Does that work?

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

```julia
pkg> st

```

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

Should I try to switch to 1.8.2?

I also tested on 1.6.2, which also works for me.

The tests pass using Julia 1.8.2 on Linux…

passes, but when I try

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

I was running:

```julia
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](https://ufechner7.github.io/2022/08/16/julia-projects.html)

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](https://github.com/danspielman/Laplacians.jl/issues) …

On the other hand, you can see here: [Laplacians.jl/Project.toml at master · danspielman/Laplacians.jl · GitHub](https://github.com/danspielman/Laplacians.jl/blob/master/Project.toml) 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:

```julia
C:\Users\YOTAM\.julia\artifacts\3aff78028a0bb2ad40ebc3ae7e465a52dcbe2730\bin\libcairo-2.dll

```

It exists on my computer.

Does this path exist:

```julia

or this one:
