IJulia problem?

Now, I noted that if I copy the notebook to another folder, the code runs, but why?

As explained in the IJulia manual,

The default Jupyter kernel that is installed by IJulia starts with the Julia command line flag --project=@.. A Project.toml (or JuliaProject.toml) in the folder of a notebook (or in a parent folder of this notebook) will therefore automatically become the active project for that notebook. Users that don’t want this behavior should install an additional IJulia kernel without that command line flag (see section Installing additional Julia kernels).
