Precompile cache misses

[ZenanH]

Hi, I'm using PythonCall.jl in my Julia package, but I found that it always precompiles this package.

[ Info: Precompiling Newenv [10636705-ebed-4bed-86c5-f04e3a3b5270] (cache misses: dep uuid changed (2))

Is this an expected behavior or is there something wrong with my usage? Below is my code.

module Newenv

using PythonCall

const meshio = Ref{Py}()

function __init__()
    meshio[] = pyimport("meshio")
    println("Newenv initialized")
end

greet() = print("Hello World!")

end # module Newenv

I cd to path/to/Newenv.jl and launch Julia, than type dev . to install this package.

precompile every time:

What makes you think this is caused by PythonCall?

[ZenanH]

oh, sorry it is my just a guess, since only PythonCall is used in the module file?

[Beforerr]

I could reproduce it with only using PythonCall in Julia version 1.11.3 when using this module in deps of other module. (This does not happen in the Newenv itself).

But this might be a Julia precompileing issue, I am not sure.

module Newenv
using PythonCall
end

I am also seeing this happen when all the package code does is load PythonCall.
