This repository contains a cross-platform installer for the Julia programming language.
The installer also bundles a full Julia version manager called juliaup
. One can use juliaup
to install specific Julia versions, it alerts users when new Julia versions are released and provides a convenient Julia release channel abstraction.
The Windows version of this installer is considered production ready. The Linux and Mac versions are prerelease versions that should not be used in production environments.
On all platforms it is recommended that you first uninstall any previous Julia versions and undo any modifications you might have made to put julia
on the PATH
before you install Julia with the installer in this repository.
On Windows Julia and Juliaup can be installed directly from the Windows store here. One can also install exactly the same version by executing
winget install julia -s msstore
on a command line.
If the Windows Store is blocked on a system, we have an alternative MSIX App Installer based setup. Note that this is currently experimental, please report back successes and failures here. To use the App Installer version, download this file and open it by double clicking on it.
Juliaup can be installed on Linux or Mac by executing
curl -fsSL https://install.julialang.org | sh
in a shell. Note that the Mac and Linux version are considered prerelease, have known bugs and might often break.
One can pass various command line arguments to the Julia installer. The syntax for installer arguments is
curl -fsSL https://install.julialang.org | sh -s -- <ARGS>
Here <ARGS>
should be replaced with one or more of the following arguments:
--yes
(or-y
): Run the installer in a non-interactive mode. All configuration values use their default.--default-channel <NAME>
: Configure the default channel. For example--default-channel lts
would install thelts
channel and configure it as the default.
Important note: As of now, we strongly recommend to install Juliaup via the curl
command above rather than through OS-specific software repositories (see below) as the Juliaup variants provided by the latter currently have some drawbacks (that we hope to lift in the future).
brew install juliaup
On Arch Linux, Juliaup is available in the Arch User Repository (AUR).
On openSUSE Tumbleweed, Juliaup is available. To install, run with root privileges:
zypper install juliaup
Once you have installed Juliaup, julia
is on the PATH
, and on Windows there is a start menu shortcut and it will show up as a profile in Windows Terminal. Any of those will start Julia. The VS Code extension will also automatically find this Julia installation.
Here are some of the things you can do with juliaup
:
juliaup list
lists all the available channels.juliaup update
installs the latest available Julia version for all your channels.juliaup update release
updates therelease
channel to the latest version.juliaup status
shows you which Julia versions you have installed and which one is configured as the default.juliaup add 1.5.1
adds Julia 1.5.1 to your system (it can then be launched via the commandjulia +1.5.1
).juliaup default 1.5.3
configures thejulia
command to start Julia 1.5.3.juliaup default 1.6
configures thejulia
command to start the latest 1.6.x version of Julia you have installed on your system (and inform you if there is a newer version in 1.6.x available).juliaup default release
configures thejulia
command to start the latest stable version of Julia (this is also the default value).juliaup remove 1.5.3
deletes Julia 1.5.3 from your system.juliaup add 1.6.1~x86
installs the 32 bit version of Julia 1.6.1 on your system.juliaup default 1.6~x86
configures thejulia
command to start the latest 1.6.x 32 bit version of Julia you have installed on your system.juliaup link dev ~/juliasrc/julia
configures thedev
channel to use a binary that you provide that is located at~/juliasrc/julia
. You can then usedev
as if it was a system provided channel, i.e. make it the default or use it with the+
version selector. You can use other names thandev
and link as many versions intojuliaup
as you want.juliaup self update
installs the latest version, which is necessary if new releases reach the beta channel, etc.juliaup self uninstall
uninstalls Juliaup. Note that on some platforms this command is not available, in those situations one should use platform specific methods to uninstall Juliaup.juliaup
shows you what other commands are available.
The available system provided channels are:
release
: always points to the latest stable version.lts
: always points to the latest long term supported version.beta
: always points to the latest beta version if one exists. If a newer release candidate exists, it will point to that, and if there is neither a beta or rc candidate available it will point to the same version as therelease
channel.rc
: same asbeta
, but only starts with release candidate versions.- specific versions, e.g.
1.5.4
. - minor version channels, e.g.
1.5
. - major version channels, e.g.
1
.
All of these channels can be combined with the ~x86
, ~x64
or ~aarch64
suffix to download a specific platform version.
To launch the default Julia version simply run julia
in your terminal.
To launch a specific Julia version, say in channel release
, run julia +release
.
Juliaup by default downloads julia binary tarballs from the official server "https://julialang-s3.julialang.org".
If requested, the environment variable JULIAUP_SERVER
can be used to tell Juliaup to use a third-party mirror server.
For juliaup developers, information on how to build juliaup locally, update julia versions, and release updates can be found in the wiki https://github.com/JuliaLang/juliaup/wiki
To use unstable preview versions of juliaup (e.g. to gt a patch before it makes it into the latest release), use
curl -fsSL https://install.julialang.org/releasepreview | sh
This JuliaCon 2021 talk is a short introduction to Juliaup. Note that the video was recorded before the Linux and Mac versions were finished, but all the information about juliaup
itself applies equally on Linux and Mac.
This JuliaCon 2022 talk provides some background on the design of Juliaup.
