Assume I have a package `X` in the default environment `v1.0`. Now I switch to a custom environment, e.g. `activate whatever`. By default, `using X` will work despite the fact that I never added `X` to `whatever`, because (AFAIU) the package manager will check all `DEPOT_PATH` paths, which includes `v1.0`, where `X` will be found.

Is there a way, except just modifying the DEPOT\_PATH, to tell Julia to be more strict and only look for packages in the current environment?

The package manager is not involved in calls to `using`, and I think you mean `LOAD_PATH` instead of `DEPOT_PATH`. The load path decides what you can `using`, and what `X` means in `using X`, but when the given package has been determined, julia will look for the installation of that package in all `DEPOT_PATH`s.

You can modify the load path to include only your home project/active project as follows:

```julia
$ export JULIA_LOAD_PATH=@
$ julia -E 'Base.load_path()'
String[] # Can't load anything.
$ julia --project=. -E 'Base.load_path()'
["/home/fredrik/Project.toml"] # Can only load whats in this Project.toml file.

```
