Installation

The official juliaup utility (GitHub) is the most user-friendly way to install and maintain your Julia installation. This tool will automatically check for updates to Julia itself and can be used to manage installations of multiple versions of Julia on the same computer, if desired.

Windows

This tool can be installed on a Windows computer via the Windows Store (here). Alternatively, it can be installed using Microsoft's winget tool by executing

winget install julia -s msstore

macOS

Linux

⚠ Note
For Linux users: the Julia maintainers do not recommend installation via your OS package manager (e.g. apt-get, dnf, pacman, etc). As of 2023, these Julia packages remain unofficial and can be prone to bugs.

The REPL

Package Manager

There are two ways to interact with Julia's package manager: an interactive mode available inside the REPL, and via the native Pkg package.

To enter the interactive package manager, simply press the right-bracket key ] from the Julia REPL.

julia> ]

Documentation Browser

Offline documentation for Julia functions and operators is available via an interactive mode within the REPL, similar to Matlab's help command.
