I get a long list of errors ending in “file not found” when I click on the kernel icon.

Please give more details about the problem. Which version of Julia do you have installed? Do you have the IJulia package installed? How did you install Jupyter?

Windows 10. Julia 1.10. IJulia is installed. I don’t have this problem with Julia 0.70. Here’s the lst part of the error msgs;

have you tried (in Julia 1.1.0) to do `] build IJulia`?

Any time you change the location of Julia (e.g. moving it to a new directory or installing a new version with a different name) you must re-run `build IJulia` (in the Julia terminal): [GitHub - JuliaLang/IJulia.jl: Julia kernel for Jupyter](https://github.com/JuliaLang/IJulia.jl#updating-julia-and-ijulia)

we just had the same issue, we solved it by setting `JULIA_DEPOT_PATH` from bash before building IJulia. If it was set from within Julia by pushing to `DEPOT_PATH` the kernel could not be found. Cf: [Julia 1.0.3 no longer finds packages in system DEPOT\_PATH · Issue #30528 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/30528#issuecomment-450504366)

rebuilding IJulia did not solve the problem

what’s the equivalent solution under Windows?

Sorry, I’m not a windows user so I have no idea.

What is JULIA\_DEPOT\_PATH supposed to be set to?

What happens if you move your `.julia` directory out of the way (just change its name) and then reinstall IJulia?

I deleted everything and just installed 1.10 and now things seem to be working
