Pluto ignores the Julia package settings

[donovaly]

I am a new user. As I don't have much disk space left at drive C:, I installed Julia to the drive J:, which is an external hard drive. To assure that Julia installs all its packages here, I setup the system variable JULIA_DEPOT_PATH to this:
J:\Julia-1.11\Packages
This works well for Julia as when I install a package using Julia's REPL, I get the packages installed indeed in J:\Julia-1.11\Packages.

But when I start Pluto, my package settings are ignored. It does not take into account that most packages are already installed and it installs them again, this time in C:\Users\>username>

Maybe I misunderstood the concept of Pluto. I thought it runs Julia but it seems it is doing its own thing, ignoring any setting of Julia (see also my issue about the threading).

Thank you for the report, I don't think Pluto currently has support for JULIA_DEPOT_PATH.

This seems to cause problems with non-ascii user folder names on windows, which came up here: https://stackoverflow.com/questions/79032378/big-problems-caused-by-chinese-usernames-in-julia

So Pluto installs packages a second time? But I want Pluto to use the packages that are already installed for Julia.

How can I specify the path in which Pluto installs packages?

This is no problem, as I assure to use ASCII-only chars in the path. The bug here is that Pluto ignores the JULIA_DEPOT_PATH setting thus it does not use the packages already installed to Julia.

However, the idea of using JULIA_DEPOT_PATH is to set a custom package installation path (for cases like mine, where C:\ is almost full and I therefore use another partition or external harddisk.
That Pluto ignores this settings, it fills up C:\ - and this is what I must avoid.
