I’m facing issue while updating julia version. I keep getting this error. Can someone explain where exactly is issue?

ERROR: failed process: Process(`ln -sf /Applications/Julia-1.9.3.app/Contents/Resources/julia/bin/julia /usr/local/bin/julia`, ProcessExited(1)) [1]

Which operating system are you using?

How and where did you execute update_julia() ?

im using mac OS Montery 12.3.1.

I excuted it in REPL .

julia> using UpdateJulia

julia> update_julia()

Does the command ln -sf /Applications/Julia-1.9.3.app/Contents/Resources/julia/bin/julia /usr/local/bin/julia work?

5

no, it doesn’t work.

6

OK. Why? The command ln -sf is trying to make a symbolic link.

Does /Applications/Julia-1.9.3.app/Contents/Resources/julia/bin/julia exist? Is /usr/local/bin/julia writable?

7

it exists but I’m not really sure about its writable or not but when i run ls -l /usr/local/bin I get

lrwxr-xr-x  1 root  wheel      64 Aug  3 16:46 julia -> /Applications/Julia-1.9.2.app/Contents/Resources/julia/bin/julia

and also before that error message I got this : ln: /usr/local/bin/julia: Permission denied So, i think its not writable.

Not a Mac user, but you can probably work around this by chowning the relevant directory. See e.g.

Note that the author of UpdateJulia.jl recommends juliaup as an alternative …

… as does the official Julia install guide:

juliaup seems to be more popular and well-tested across platforms.

I used this and it worked.

using UpdateJulia
update_julia(systemwide=false)

Also using “juliaup” works:

One can install it on terminal with curl -fsSL https://install.julialang.org | sh -s -- <ARGS>

Once done. Close terminal and open it again. Then just type juliaup update on terminal and it will do the job.
