I just downloaded the latest version of JuMP v0.21.8 and while precompiling some of the dependencies failed. Any reason why? However, the command `build JuMP` runs without any error. I am using Julia 1.6.1.

I can’t reproduce this on a clean install.

What is `import Pkg; Pkg.precompile()`?

Also `import Pkg; Pkg.status()`?

Hi @odow,

I clean wiped the `.jula/ ` folder on my machine and reinstalled the `JuMP` package. The dependencies that failed then reduced to 1. Finally, I found this [solution on stackoverflow](https://stackoverflow.com/questions/66314494/gr-jll-keeps-failing-to-precompile-where-using-julia-1-6-0-rc1-on-windows). Even though it resolves the issue, I still don’t know the reason behind it. Any leads on why this may be happening? I never faced this when I installed any package on my previous machines.

This is the first package I installed on this machine so there isn’t anything else installed.  
`Pkg.status()`  
`JuMP v0.21.8`

`Pkg.precompile()` does not return anything.

Also on running `test JuMP`, I see that `MutableArithmetics` does not pass 6 tests. Not sure if the issues are related:

```julia
Test Summary: | Pass Total
model.jl | 257 257
mutable_arithmetics.jl took 61.5 seconds.
Test Summary: | Pass Broken Total
mutable_arithmetics.jl | 1786 6 1792
nlp.jl took 9.9 seconds.
Test Summary: | Pass Total
nlp.jl | 113 113

```

Any probable reasons behind why dependencies errored or these tests fail? Thank you!

No ideas sorry.

The broken tests in MutableArithmetic are known. You can safely ignore them.

Okay. Thanks.
