I am currently using Julia version 1.7.2. on macOS Monterey with an arm processor, When I tried updating to 1.8.3 via the UpdateJulia package I received the following permission error

/dev/disk4              GUID_partition_scheme

Just wondering if there was a quick fix to this and if it is recommended to update to 1.8 from 1.7? Any tips would be appreciated thanks!

You might be able to do

update_julia(; systemwide=false)

Thanks so much! I think this installed 1.8 as It is says that packages have been migrated from 1.7 to 1.8. However when I restart Julia and check version I am still getting

VERSION
v"1.7.2"

How do you launch julia?

I launched it through VScode?

thanks for helping with this! so when I ran update_julia(; systemwide=false) it said

Please add /Users/kat/.local/bin to path

but when I added it to Julia:Executable Path I keep getting a system error in Julia. So I tried to check if I had the right path, but when I typed whereis Julia into terminal it just returns :Julia . I tried updating VScode but that didn’t seem to do anything.

Try making Julia: Executable Path

/Users/kat/.local/bin/julia

Wow that did it! thanks so much it would’ve taken me days without your help!

This is a sum up of all of @jd-foster’s answers for future reference and any other less savvy novices since I asked so many questions to get it working.

to update Julia within the REPL try

]add UpdateJulia
using UpdateJulia
update_julia()

if this does not work try

update_julia(; systemwide=false)

UpdateJulia will then display the following message:

Please add /Users/user/.local/bin to path

In VSCode:

  1. Click on Extensions on the left hand side
  2. Select or type in Julia.
  3. Click on the gear icon
  4. Select Extension Settings
  5. Under Julia: Executable Path - paste the path provided by UpdateJulia + /julia so
/Users/user/.local/bin/julia

You can check if the updated version is installed by typing VERSION into the REPL and update packages with
