Julia in Jupyter: kernel error ("Failed to precompile in IJulia") - jupyter-notebook

Question

Having added Julia to Jupyter, I encounter the following problem:
I wonder if there is a fix for this? For example, by changing the path to \.julia to a local drive (C:\ in my case is in fact not).

Answer 1

My working solution:
rm -rfd ~/.julia/compiled
In the julia REPL:
using Pkg
Pkg.update()
Pkg.precompile()
Assuming we previously installed / updated IJulia, then from Julia REPL:
using IJulia
installkernel("Julia")
At this point launch the notebook from the command line
jupyter notebook --browser="brave"

Answer 2

I ran into the same problem when I tried to add IJulia:
julia > using Pkg
julia > Pkg.add("IJulia")
This produced similar errors to what you posted. My solution was to remove the .julia directory in my home directory:
$ rm -rf ~/.julia
Then I restarted julia and proceeded to install IJulia using the commands above, and it worked.
