Hi,

I’m brand new to Julia and was following one of the JuliaAcademy courses but unfortunately have run into a hiccup quite quickly. When I try to install IJulia in terminal, I receive the following System Error.

**(@v1.5) pkg\>** add IJulia

**Installing** known registries into `~/.julia`

I looked at some similar posts on here for troubleshooting and also tried “add Example” and “add [https://github.com/giordano/DebugArtifacts.jl.git](https://github.com/giordano/DebugArtifacts.jl.git)” but basically get the same error message as with add IJulia. This feels like an issue with the path, but I have no idea how to fix it.

Help, please!

It looks like your registry information is missing/broken/corrupted. How did you install Julia?

Hi Tamas,

A little while ago I had downloaded JuliaPro, and then for the Julia Academy tutorial, I downloaded Julia and nteract. All of the downloads were from: [https://juliacomputing.com/](https://juliacomputing.com/)

Thanks for your help!

Best,

Natalya

I can’t help with JuliaPro; I would recommend using the binaries from

Hi Tamas,

Thanks for working through this with me. I really want to use Julia and figure out why it’s not working.

I redownloaded Julia v1.5.1 from [julialang.org](http://julialang.org) and opened it. However, I’m still getting the same error. Here’s the output:

Help please!

Best,

Natalya

I would recommend that you consider deleting the `~/.julia` folder, and allowing Julia to recreate it.

This should be the easiest way to recover, but it will also lose customizations and locally developed packages; however, since you are new to Julia you may not have any of these. Or you can keep everything by just renaming it to eg `~/.julia-backup` which allows you to experiment.

Hi Tamas,

Thank you!! Deleting the ~/.julia folder and then reinstalling Julia fixed the problem!! I’m able to work through the tutorials now, and I have to say, I LOVE Julia. It makes so much intuitive sense. I am really excited to keep working through the basic tutorials and move into the more advanced applications.

Best,

Natalya
