Hi, I’m trying to figure out how to setup IJulia for all users on my JupyterHub server.  
I know that Julia has “depots” in global locations, but I’m not sure how to install packages there. When I run Pkg.depots(), I see this:

```julia
julia> Pkg.depots()
3-element Array{String,1}:
 "/home/ubuntu/.julia"
 "/opt/julia-1.4.2/local/share/julia"
 "/opt/julia-1.4.2/share/julia"

```

Can someone help me out, or let me know if this is possible?

Ok, so I’m attempting to follow the instructions on this post ([Julia kernel on JupyterHub system-wide LDAP - #6 by barche](https://discourse.julialang.org/t/julia-kernel-on-jupyterhub-system-wide-ldap/14809/6)) and I’m running

It looks like it’s still using the local depot. How do I get it to switch to the global one?

I’ve been trying some more stuff. With the command above, it looked like sudo was interfering with the `Base.DEPOT_PATH` variable getting set. What worked was this command:

```bash
$ sudo env JULIA_DEPOT_PATH=/opt/julia-1.4.2/share/julia julia

```

This allowed me to install IJulia to the global depot. However, after that I had to run:

```bash
$ sudo mv ~/.local/share/jupyter/kernels/julia-1.4/ /usr/share/jupyter/kernels

```

so the IJulia kernel could be used globally on the system. Now the kernel works systemwide on my JupyterHub server

I’ve put together a stop-by-step guide for this:  
[https://github.com/mauro3/JupyterHubWithJulia](https://github.com/mauro3/JupyterHubWithJulia)

Note though that I’m not sure this is the “best” or even a “good” solution. But it seems to work from the little testing I did so far. One issue I’m not clear about is how it will interact with updating, in particular IJulia.

Thanks for your post, @camtheman256, which works for Julia 1.8.1 and Jupyterhub 2.02 hosted by an LXC container that is Ubuntu-20.04-based. A little update here.

1. I installed Julia to /opt/ for the ease of global availability.

```julia
sudo tar -xzf julia-1.8.1-linux-x86_64.tar.gz -C /opt/

```

1. vim /etc/bash.bashrc

```julia
# The global Julia settings to work with Jupyterhub
export JULIA_HOME="/opt/julia-1.8.1"
export JULIA_PKG_SERVER="https://mirrors.bfsu.edu.cn/julia"
export JULIA_DEPOT_PATH="$JULIA_HOME/share/julia"
export PATH="$JULIA_HOME/bin:$PATH"

```

**Note** : Here’s a [Julia Pkg Server list in Chinese](https://discourse.juliacn.com/t/topic/2969). If you’re not sure which one to choose, just use the official one: `https://pkg.julialang.org`.

1. Log out and log in to make the changes applied. Install **IJulia**.

```julia
(@v1.8) pkg> add IJulia

```

1. Create folders and move the Julia kernel.

```julia
sudo mkdir -p /usr/share/jupyter/kernels
sudo mv ~/.local/share/jupyter/kernels/julia-1.8/ /usr/share/jupyter/kernels/

ls /usr/share/jupyter/kernels/julia-1.8/
kernel.json logo-32x32.png logo-64x64.png

```

1. After restarting Jupyterhub or its kernel from the webpage, the Julia 1.8.1 kernel option should appear.

I haven’t run into any permission problems to install Julia and IJulia that way.

Same here, when a user tries to install a package, e.g. Pkg.add(“CSV”) it results in
