Ok this is a bit cryptic - I think after looking this up the problem is that Blink.jl is restricted to Mux.jl v0.7 which uses HTTP.jl <1.0, but Pluto now requires HTTP.jl >1.0 .

So there are the following possibilities:

  • Separate the projects using Blink and Pluto into different environments. This is the general recommendation - I guess if you run a pluto notebook, you don’t need Blink. You could for instance call Pluto always with Julia started by
julia --project=@pluto

This creates a separate environment where you just add Pluto.

  • If you must use them together, you are “stuck” with an older Pluto which still may work well
  • If it is a necessity for survival to have both Blink and newest Pluto, kindly ask the Blink developers to update their dependencies - either via an issue or - after trying the updaete yourself - via a PR.
