Hi,

I just updated all packages ]up and out of a sudden precompilation failed which worked before.

## Precompiling failed after ]up

```julia

I’ve seen this similar issue [Failed to precompile DifferentialEquations v1.6.2](https://discourse.julialang.org/t/failed-to-precompile-differentialequations-v1-6-2/81447) however it doesn’t help for me here.

Any help is highly appreciated

EDIT: I guess it has something todo with Trebuchet.jl package

Does installing in a clean environment work?

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

```

```julia
using Pkg
pkg"add DiffentialEquations"
pkg"add DiffEqFlux"

```

If that works, you can try to add the other packages you need one by one until it fails.

Then we would know which package causes the failure.

Thank you for the systematic approach - I will try it

It is indeed `Trebuchet.jl` package. When removing it and updating everything compiles. When adding it again afterwards, I get the following downgrades:

I have no clue what is happening here. Trebuchet does not have any compat entries related to these packages [Trebuchet.jl/Project.toml at master · FluxML/Trebuchet.jl · GitHub](https://github.com/FluxML/Trebuchet.jl/blob/master/Project.toml)

Did you add the master branch of Trebuchet as suggested in the README?

```julia
using Pkg
pkg"add Trebuchet#master"

```

?

It probably forces OrdinaryDiffEq v5 via an old bound. It doesn’t need to though. @dhairyagandhi96 can we get that bumped?
