Julia

Install Julia

I recommend installing Julia using the juliaup tool, which will let you easily manage versions in the future and works seamlessly with VS Code. The instructions can be found at the JuliaUp GitHub repository, but we will summarize them here.

Installing Juliaup on Windows

If your computer uses Windows, you can install Juliaup from the Windows Store.

Installing Juliaup on MacOS

If you have a Mac, open a terminal (such as the Terminal app) and enter:

curl -fsSL https://install.julialang.org | sh

Installing Julia 1.11.5

Once you install Juliaup, install Julia version 1.11.5 by opening a terminal (in MacOS or Linux) or the command line (in Windows) and entering:

juliaup add 1.11.5
juliaup default 1.11.5

This will install Julia 1.11.5 and make it the default version, which should maximize package compatibility throughout this course. Going forward, if you want to add new versions or change the default, you can follow the Juliaup instructions. If your code returns an error when you try to load packages, it’s possible you have a different version of Julia: in this case, delete Manifest.toml¹ and re-run a code block that contains

¹ Not Project.toml!

import Pkg
Pkg.activate(@__DIR__)
Pkg.instantiate()

The line Pkg.instantiate() will install the right package versions for your installation and create a new Manifest.toml file.
