Hi, is there way to use a Module only locally?

If I create a remote worker (e.g. with ssh on a different machine), then when I run `using Module`, the module needs to be installed on the remote host as well (Otherwise I get “ERROR: on worker 2: ArgumentError: Package … is required but does not seem to be installed”).

The only command I’m aware of to do so would be `@fetchfrom 1 using Module`, but it does not work (ERROR: syntax: “using” expression not at top level).

I understand that it can make sense to load code everywhere (and actually, I thought we should use `@everywhere` in that case), but some packages are used only on the main process, and it’s useless to install them on other workers in that case.

I might be misunderstanding your question but isn’t the standard approach of `using LocalOnlyPackage` and `@everywhere using LocalAndRemotePackage` doing what you need?

Well that’s what I thought, but then why do I get a “package not installed” error from worker 2 when I run `using SomePackage` on proc 1? Is it a bug rather than the expected behavior?
