How to change default save location for downloaded package with “add” command?

Viewed 76

I want the packages to be downloaded and saved in drive E instead of drive C. I read about JULIA_DEPOT_PATH in this article, however I don't know the specific steps to do, could you please take a moment to make a demonstration for me?

Assuming that you use Windows it is just enough to do:

SET JULIA_DEPOT_PATH=C:\your\path

Please follow this example

C:\Users\pszufe>SET JULIA_DEPOT_PATH=C:\Users\pszufe\mypath

C:\Users\pszufe>julia
