Configure your system to evaluate external Julia code.

For Mac...

Install Julia

Julia can be installed for Mac through a package repository such as Homebrew, or by using the installer downloaded from https://julialang.org/downloads.

Install the ZeroMQ package for Julia

Install the ZeroMQ package for Julia using the Julia package manager, Pkg. Start a Julia session and execute the following:

julia> using Pkg

julia> Pkg.add("ZMQ")

julia> Pkg.add("JSON")

Verify the installation

If the installation was successful, FindExternalEvaluators will find it automatically:

  • If you have more than one version of Julia installed on your machine, you can use RegisterExternalEvaluator to make a specific installation of Julia the default.

Evaluate Julia code

Use ExternalEvaluate with the Julia installation to evaluate Julia code:

Alternatively, use a Julia code cell to evaluate Julia code:

sqrt(36)
  • If ExternalEvaluate fails, it is likely that the ZMQ and JSON packages are not installed. Make sure you install the packages with the specific installation of Julia that you would like to use.
