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.
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.
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 and note the installation directory. The installation directory should look something like C:\Users\JohnDoe\AppData\Local\Programs\Julia 1.5.3, please note this path.
To invoke Julia by simply typing julia in the command line, the Julia executable directory needs to be added to PATH. Perform the following steps to add Julia to PATH.
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 1.5.3\bin.
Click OK. You can now run Julia from the command line, by typing julia!
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 1.5.3\bin.
Click OK. You can now run Julia from the command line, by typing julia!
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 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).
On macOS, a Julia-<version>.dmg file is provided, which contains Julia-<version>.app. Installation is the same as any other Mac software: drag the Julia-<version>.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.
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).
rm -f /usr/local/bin/julia
ln -s /Applications/Julia-1.5.app/Contents/Resources/julia/bin/julia /usr/local/bin/juliaThis code creates a symlink to a Julia version (here 1.5) of your choosing. To launch Julia, simply type julia inside your shell and press return.
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.
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-1.5.3.
wget https://julialang-s3.julialang.org/bin/linux/x64/1.5/julia-1.5.3-linux-x86_64.tar.gz
tar zxvf julia-1.5.3-linux-x86_64.tar.gzThe 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.
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.
The following distribution-specific packages are community contributed. They may not use the right versions of Julia dependencies or include important patches that the official binaries ship with. All these 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.
If you use Chocolatey for package management, you can install the latest Julia release by executing the following one-liner, in either a powershell or command prompt:
choco install julia --confirmChocolatey automatically creates a shim for the Julia executable, so you simply type julia to run Julia in the terminal. When a new version is released simply execute choco upgrade julia --confirm. If you want to uninstall Julia run choco uninstall julia --confirm.
Julia can be installed using the Homebrew package manager as follows:
brew install --cask juliaThis automatically puts the binary into a directory in the user's PATH, so you can simply type julia to run Julia in the terminal.
A Copr repository is provided for Fedora, RHEL, CentOS, Scientific Linux and Oracle Enterprise Linux systems to allow for automatic updating to the latest stable version of Julia.
If you are using RHEL, CentOS, Scientific Linux or Oracle Enterprise Linux (version 5 or higher), first enable EPEL for your distribution version. Then follow the steps below.
If you are using Fedora (version 19 or higher), directly run:
sudo dnf copr enable nalimilan/julia
sudo yum install juliaIf you are using CentOS (version 7 or higher), directly run:
sudo yum-config-manager --add-repo https://copr.fedorainfracloud.org/coprs/nalimilan/julia/repo/epel-7/nalimilan-julia-epel-7.repo
sudo yum install juliaIf both dnf and yum-config-manager are not available for your distribution, download the relevant .repo file from the Copr webpage, copy it to /etc/yum.repos, and run the second command.
Note that Fedora guidelines advise against uploading new breaking releases to official repositories: therefore your distribution will not provide the new major versions of Julia which were published after it. When reporting issues, please ensure you are using the latest available release by using one of the Copr repositories displayed on this page. In order to use nightly Julia builds, replace nalimilan/julia with nalimilan/julia-nightlies in the instructions above. These can then be updated with yum upgrade julia.
Recent Debian/ubuntu distributions include their own build of Julia, which can be installed in the usual way. Check the versions of Julia provided in Ubuntu and Debian. If this is not the version of Julia you want, you will need to use the official binaries.
sudo apt install juliaThe Arch User Repository has a package for Julia that is built from the official binaries of Julia. To install it run:
sudo pacman -S base-devel git
git clone https://aur.archlinux.org/julia-bin.git
cd julia-bin
makepkg -siJulia is available in the Ports Collection. To install from the FreeBSD binary package manager, pkg, run
pkg install julia
