Kernal does not connect

[LilithHafner]

When I install and launch a notebook session through IJulia (to try to diagnose LilithHafner/BasicAutoloads.jl#9), the kernel does not connect:

Launches a web browser. When I click on new and select Julia 1.11.1, I get a notebook. It says "Kernel status: connecting" for a minute or so and then says "Kernel status: disconnected" as tooltip text when mousing over the lightning bolt icon.

Any idea what's going wrong here? I get the same issue on asahi linux and on aarch mac.

IJulia should be installed in the global environment.

If you update Julia with juliaup, then you need to re-run build IJulia because the location of the julia binary has changed. See JuliaLang/juliaup#857

[LilithHafner]

Installing IJulia in the global environment fixed it.
