Pluto is unavaliable

[BrettKnoss]

I have Julia 1.8.0 for Mac ARM on an M1 Max with Monterey 12.4 and the Pluto package appears to execute, but Pluto is not found at the correct location on my system.

HTTP ERROR 404

Press Ctrl+C in this terminal to stop Pluto

[BrettKnoss]

The issue is not with Julia 17.2 stable, only Julia 18.0 beta

[rikhuijzer]

Are you running an old HTTP and Pluto version or the newest? Here it works on Julia 1.8.0-beta3 with Pluto 0.19.5 and HTTP 0.9.17 on Linux. Your issue doesn't look MacOS or M1 specific. Related upstream issue: JuliaLang/julia#41995

Julia 17.2 stable, only Julia 18.0 beta

1.7.2 and 1.8.0-beta3 probably

EDIT: Nope. Pluto 18.0

[BrettKnoss]

I reinstalled 18.0, so it should be a latest version, but I didn't see that. Does HTTP have to do with my browser, and how do I check the version of Pluto?

I reinstalled 18.0, so it should be a latest version

Currently, Pluto.jl is at version 0.19.5. Are you installing everything in your global environment? Probably that's what causing your Pluto version to be outdated. You can try

julia> ]

pkg> activate --temp

pkg> add Pluto

pkg> <Backspace>

julia> import Pluto; Pluto.run()

Does HTTP have to do with my browser

Yes also, but I meant HTTP.jl

and how do I check the version of Pluto?

Type the following where you would normally type Pluto.run():

julia> ]

pkg> st

I'm gonna close this because it appears that you're running an outdated Pluto version.
