I am very interested in using the [AlphaShapes.jl](https://github.com/harveydevereux/AlphaShapes.jl) package.
However after installation, I get the following error when I try to load it for the first time. I would appreciate any help with troubleshoorting.

Can you share the output of:
```julia-auto
versioninfo()
```
?
I installed it on Linux on Julia 1.12, and that worked.
However, the package is not well-maintained; it lacks working unit tests for all operating systems.

TLDR you have an old version of the package JLLWrappers in your environment (\

Mine is 1.8.5. I have updated my entry and mentioned this now.
Thank you for sharing your experience with this package. I am mostly in search of a triangulation algorithm that works for submanifolds embedded in Euclidean space. The Delauney method does not quite do the job, as it creates simplices of the same dimension as the ambient space.

Thanks for the feedback. My version is 1.8.5. I was not aware of this feature called `JLLWrappers`. Could I request you to point me towards a page where I could know more about this ?

JLLWrappers.jl is simply a package you have in your environment. In the REPL type
```julia-auto
]status -m JLLWrappers
```
to see the version of the package (`]` is for entering the [Pkg REPL mode](https://pkgdocs.julialang.org/v1/getting-started/#Basic-Usage)). You should see that `JLLWrappers` is older than v1.7.0.

The key point: Always use project-specific, not global, environments, as explained [here](https://ufechner7.github.io/2022/08/16/julia-projects.html).
And use:
```julia-auto
using Pkg
Pkg.status()
```
to check if the versions of your key packages are up to date and that no packages you no longer need are in your environment.
And Julia 1.8.x is no longer maintained. If possible, try updating to Julia 1.10.x or 1.12.x Switching Julia versions is easy with [juliaup](https://github.com/JuliaLang/juliaup) .
