Platform Specific Instructions for Official Binaries

All official Julia binaries produce portable installations. Once installed, the directory in which Julia was installed can be moved to a different location on the same computer, or even to a different computer.

The instructions here refer to the latest stable release of Julia. If you are using the LTS version or an older version, please substitute the appropriate version number in the instructions.

Windows

Julia is available for Windows 7 and later for both 32 bit and 64 bit versions.

We highly recommend running Julia using a modern terminal, such as installing the Windows Terminal from the Microsoft Store.

Install Julia in 4 simple steps!

Download the Windows Julia installer from https://julialang.org/downloads/. Note, the 32-bit Julia binaries work on both 32-bit and 64-bit Windows (x86 and x86_64), but the 64-bit Julia binaries only run on 64-bit Windows (x86_64).
Run the installer
Check the Add Julia To PATH to automatically add Julia to Environment Variables

Invoke Julia by simply typing julia in your preferred terminal

Adding Julia to path for older releases

For older (<= Julia 1.5.4) downloads, note the installation directory at the time of installation. The installation directory should look something like C:\Users\JohnDoe\AppData\Local\Programs\Julia 1.7.3, please note this path.

Then add the Julia executable directory to PATH by performing the following steps.

Adding Julia to PATH on Windows 10,

Open Run (Windows Key + R), type in rundll32 sysdm.cpl,EditEnvironmentVariables and hit enter.
Under either the "User Variables" or "System Variables" section, find the row with "Path", and click edit.
The "Edit environment variable" UI will appear. Here, click "New", and paste in the directory noted from the installation stage. This should look something like C:\Users\JohnDoe\AppData\Local\Programs\Julia 1.7.3\bin.
Click OK. You can now run Julia from the command line, by typing julia!

Adding Julia to PATH on Windows 7 or 8

Open Run (Windows Key + R), type in rundll32 sysdm.cpl,EditEnvironmentVariables and hit enter.
In the System Variables window, highlight Path, and click Edit.
In the Edit System Variables window, move the cursor to the end of the field.
If there is no semicolon at the end, add it and paste in the path to the bin folder within the installation directory noted earlier. This path should look something like C:\Users\JohnDoe\AppData\Local\Programs\Julia 1.7.3\bin.
Click OK. You can now run Julia from the command line, by typing julia!

Windows 7 / Windows Server 2012 Installation Notes

Windows 7 / Windows Server 2012 users also need to install:

the TLS easy_fix for the package manager to work, see this Discourse thread for more details.
Windows Management Framework 3.0 or later to include PowerShell 3.0 or later.

Uninstallation

Uninstallation is preferably performed by using the Windows uninstaller. The directory in %HOME%/.julia can then be deleted if you want to remove all traces of Julia (this includes user installed packages).

macOS

On macOS, a julia-1.7.3-mac64.dmg file is provided, which contains Julia-1.7.app. Installation is the same as any other Mac software: drag the Julia-1.7.app to Applications Folder's Shortcut. The Julia download runs on macOS 10.9 Mavericks and later releases. You can build from source for macOS 10.6 Snow Leopard (possibly earlier versions as well) and 32-bit but neither are fully supported.

You can launch Julia by opening the Julia app like any other application.

Optional: Add Julia to PATH

If you want to launch Julia from the command line, first open a new terminal window, then run the following snippet from your shell (e.g., using the Terminal app, not inside the Julia prompt).

sudo mkdir -p /usr/local/bin
sudo rm -f /usr/local/bin/julia
sudo ln -s /Applications/Julia-1.7.app/Contents/Resources/julia/bin/julia /usr/local/bin/julia

This code creates a symlink to a Julia version (here 1.7) of your choosing. To launch Julia, simply type julia inside your shell and press return.

Uninstallation

You can uninstall Julia by deleting Julia.app and the packages directory in ~/.julia. Multiple Julia.app binaries can co-exist without interfering with each other. If you would also like to remove your preferences files, remove ~/.julia/config/startup.jl and ~/.julia/logs/repl_history.jl.

Linux and FreeBSD

It is strongly recommended that the official generic binaries from the downloads page be used to install Julia on Linux and FreeBSD. The following set of commands downloads the latest version of Julia into a directory named julia-1.7.3.

wget https://julialang-s3.julialang.org/bin/linux/x64/1.7/julia-1.7.3-linux-x86_64.tar.gz
tar zxvf julia-1.7.3-linux-x86_64.tar.gz

Running Julia

The generic Linux and FreeBSD binaries do not require any special installation steps, but you will need to ensure that your system can find the julia executable. The directory where Julia is installed is referred to as <Julia directory>.

To run Julia, you can do any of the following:

Invoke the julia executable by using its full path: <Julia directory>/bin/julia
Create a symbolic link to julia inside a folder which is on your system PATH
Add Julia's bin folder (with full path) to your system PATH environment variable

To add Julia's bin folder (with full path) to PATH environment variable, you can edit the ~/.bashrc (or ~/.bash_profile) file. Open the file in your favourite editor and add a new line as follows:

export PATH="$PATH:/path/to/<Julia directory>/bin"

Apart from this, there are several ways through which you can change environment variable. You can follow this guide to find out a way convenient for you.

Julia installs all its files in a single directory. Deleting the directory where Julia was installed is sufficient. If you would also like to remove your packages, remove ~/.julia. The startup file is at ~/.julia/config/startup.jl and the history at ~/.julia/logs/repl_history.jl.

Cross-platform installer

Jill.py is a community-maintained command-line tool that automates the installation workflow for all platforms. After installing this using pip install jill -U, you can then use jill install to install the current stable release, and jill install latest to install the nightly builds.

Juliaup

An installer and version manager for Julia called juliaup is available in the Microsoft Store. It can be used to install specific Julia versions or update to the latest release. This package handles all PATH related aspects of Julia, and alerts users when new Julia versions are released.

A Brief Note About Unofficial Binaries

There are a variety of distribution-specific packages that are community contributed. They may not use the right versions of Julia dependencies or include important patches that the official binaries ship with. All such distributions are community maintained, and hence they may not always have the latest versions of Julia, and sometimes, the instructions may not work. In general, bug reports will only be accepted if they are reproducible on the official generic binaries on the downloads page.
