Using JuliaSim Packages Locally via the JuliaHub Registry

To use JuliaSim packages on your local machine, you will need to add JuliaHub as a registry on your computer. To do this, you need to download an authentication token from the platform.

Adding the JuliaHub registry

Start a Julia session and install the PkgAuthentication package. This package can be used for both initial setup and to stay connected to the registry.

julia> using Pkg
julia> original_active_project = Base.active_project()
julia> try
  withenv("JULIA_PKG_SERVER" => nothing) do
    Pkg.activate("v$(VERSION.major).$(VERSION.minor)"; shared = true)

Next, configure Julia to be aware of's package server:

julia> using PkgAuthentication
julia> PkgAuthentication.install("")

Then add all known registries on, including the JuliaHub registry, from the "Pkg REPL" (by pressing ] from the Julia REPL), using

julia> Pkg.Registry.add()

The command above will only work on Julia v1.8 and later. On versions prior to v1.8 use the pkg> REPL command registry add instead.

This will open up a new browser window or tab and ask you to sign in to or to confirm authenticating as an already logged in user.

Once logged in, the browser tab can be closed. Julia will be authenticated with the package server at and download all available registries.


This will also change the package server to for all Julia sessions that run startup.jl.

Staying connected to the JuliaHub registry

The authentication token will expire after a while, so it is convenient to enable an automatic mechanism for renewal. This can be achieved using the previously installed PkgAuthentication package, by adding the following snippet to your local <home directory>/.julia/config/startup.jl file.

Base.eval(Module(), quote
    using PkgAuthentication

This will ensure that whenever a Pkg operation is performed that an up-to-date authentication token is available either silently or through another browser interaction.

Supported Packages

The following JuliaSim packages currently support usage through the JuliaHub registry:
