when user first opens Julia without a ~/.julia, this is a bit annoying because the project path is read-only, despite the fact that : is the first in JULIA_DEPOT_PATH.

in fact, this is still the case even if ~/.julia exists and the only fix seems to be manually creating a environment somehow

KristofferC commented 2 years ago

So what do you suggest should be done here?

Moelf commented 2 years ago

when therer's :, simply put ~/.julia/environments/v@ as the depot?

Probably Pkg should not accept an environment from lower depots if the intention is to modify it (e.g. in add).
