SolvedIJulia.jl Previously Installed Jupyter distribution cant find Julia

223

So I have a previously installed version of conda and jupyter that I want to use. Since the conda distribution for IJulia is currently not working on windows, I attempted to simply install Julia, change the ENV variable to

ENV["JUPYTER"] = "C:\\Users\\Haru\\Miniconda3\\share\\jupyter\\"

then installed IJulia the normal way:

using Pkg
Pkg.add("IJulia")

and then i opened my previous Jupyter distribution and when i attempted to start the Julia Kernel i recieved the error:

FileNotFoundError: [WinError 2] The system cannot find the file specified

Is this because of Jupyter not knowing where Julia is installed? How do I tell it where for it to look for Julia?

You don't need to set JUPYTER — the kernel configuration file is installed in a location that should be visible to all Jupyter installations. Have you tried Pkg.build("IJulia") in case your Julia installation has moved since you first installed it?
