Hey! how are you guys doing?
I’m dealing with a rather obnoxious problem. I want to run Julia through Jupyter notebooks, I’ve Windows 10 and Python (through Anaconda suite) and as I was dealing with some cleaning I’ve uninstalled Anaconda and Julia, cleaned directories, temp files and reboot my PC. After that I’ve installed Anaconda and Julia in a new directory (D disk instead of C, differents folders), but I can’t get anything from Julia.
I just keep getting errors of “IJulia has no known versions!”, even though I’ve created a new environment to overcome the chance of a bad installation or dependencies issues.
Do you have any idea where the problem could be?

What happens when you do
```julia
julia> using IJulia
```
in the REPL?

Wow! that was a fast response:
Sorry, I’ve pasted the wrong screencap

Okay so it looks like you haven’t installed the Julia package which actually enables the interaction with Jupyter. You need to do:
```julia
julia> ] # (hit ] to enter the pkg REPL mode)
(@v1.5) pkg> add IJulia
```
to install the `IJulia` package. Note that by default this will just install a private Miniconda distribution to deal with all Python related stuff, if you want to use your pre-existing Anaconda installation check out the link in the package Readme [here](https://github.com/JuliaLang/IJulia.jl) to figure out how to do that (althouh honestly unless you’re heavily constrained in terms of storage space I wouldn’t bother)

Thanks again! I’ll do the miniconda installation as you suggest!
I just keep getting an error:

That’s odd, is this a fresh install? Maybe related to moving to the D drive? In any case this suggests something’s wrong with your package registry, have a look here: [Pkg\> add results in “no known versions” errors for “Flux” and “Plots”](https://discourse.julialang.org/t/pkg-add-results-in-no-known-versions-errors-for-flux-and-plots/46457)

You are the best! I think that there was some remain of the previous installation. thank you so much! 😃
