I am using julia-1.10.0. I am using julia remotely on the Rocky 9 VM.

I am getting the following error in the pre-compilation of the DifferentialEquations.jl package:  
PkgPrecompileError: The following 1 direct dependency failed to precompile:

What is the output of:

```julia
using Pkg
Pkg.status()

```

Did you try it in a clean environment, e.g.

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

```

and then in Julia:

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

```

And what is the output of:

```julia
versioninfo()

```

You can use any directory, but preferably not `.julia`…

I mean, usually you create a per-project environment (= Project.toml + Manifest.toml) in the main folder of your project…

Thanks for the prompt reply. I will try it again after creating a new environment directory.

How much memory (RAM) do you have?

```julia
free -h

```

And if you try to add only BoundaryValueDiffEq?

```julia
]
rm DifferentialEquations
add BoundaryValueDiffEq

```

Just to narrow down the problem.

Do you actually need this package? If yes, report a bug at [Issues · SciML/BoundaryValueDiffEq.jl · GitHub](https://github.com/SciML/BoundaryValueDiffEq.jl/issues) .

If not, just install what you need. I usually only install `OrdinaryDiffEq` which is much smaller and has all the functionality I need…

Sometimes there are also corrupt intermediate files in the `.julia` folder…

You could try to delete it if you are sure there is nothing in there what you still need…

Odd that the error message throws almost no information. Try just doing LinearSolve?

Thanks for your replay. Can I skip BoundaryValueDiffEq.jl from DifferentialEquations.jl?

Thanks for your reply. I will try LinearSolve only.
