How to delete precompile cache?

General Usage

So, deeper. The crtbp_phasenraum.jl starts with

push!(LOAD_PATH, "../ODE_Integratoren/")
push!(LOAD_PATH, "./")
using ode_integratoren,ode_symplektisch,crtbp_modul,Printf

Copying and pasting those lines into julia after removing .julia and re-installing StaticArrays gives the error

julia> using ode_integratoren,ode_symplektisch,crtbp_modul,Printf
[ Info: Precompiling ode_integratoren [top-level]
┌ Warning: The call to compilecache failed to create a usable precompiled cache file for ode_integratoren [top-level]
│   exception = Required dependency hilfsfunktionen [top-level] failed to load from a cache file.
└ @ Base loading.jl:963
[ Info: Precompiling ode_symplektisch [top-level]
[ Info: Precompiling crtbp_modul [top-level]
┌ Warning: Module ode_integratoren with build ID 2121584251246112 is missing from the cache.
│ This may mean ode_integratoren [top-level] does not support precompilation but is imported by a module that does.
└ @ Base loading.jl:941

Now, the modules in crtbp_modul

push!(LOAD_PATH, "../Hilfsfunktionen/")
push!(LOAD_PATH, "../ODE_Integratoren/")
using ode_integratoren,ode_symplektisch,hilfsfunktionen,Printf,DelimitedFiles

and in ode_integratoren.jl

push!(LOAD_PATH, "../Hilfsfunktionen/")
using StaticArrays,LinearAlgebra,hilfsfunktionen

The ode_symplektisch.jl does not use anything.

This stinks of some kind of race condition.
