It reports an `ERROR` when I `using JuMP` (version: `JuMP v1.20.0`):

```julia

ERROR: LoadError: ArgumentError: Package JuMP does not have SnoopPrecompile in its dependencies:
- You may have a partially installed environment. Try `Pkg.instantiate()`

- Or, if you have JuMP checked out for development and have
  added SnoopPrecompile as a dependency but haven't updated your primary

I suppose not the first nor the second caveat apply?

Did you try:

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

```

and then at the Julia prompt:

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

```

?

Well, I ran `using JuMP` again and it worked. Thanks to everyone!

JuMP v1.20.0 does not use SnoopPrecompile, so I assume that you had something weird going on with your environment (i.e., it was probably the first bullet point).
