The first step to using Rust is to install it! There are a number of ways to
install Rust, but the easiest is to use the
rustup script. If you're on Linux
or a Mac, all you need to do is this:
Note: you don't need to type in the
$s, they just indicate the start of each command. You’ll see many tutorials and examples around the web that follow this convention:
$for commands run as your regular user, and
#for commands you should be running as an administrator.
$ curl -sf -L https://static.rust-lang.org/rustup.sh | sh
If you're concerned about the potential insecurity of using
curl | sh, please keep reading and see our disclaimer below. And feel free to
use a two-step version of the installation and examine our installation script:
$ curl -f -L https://static.rust-lang.org/rustup.sh -O $ sh rustup.sh
If you're on Windows, please download the appropriate installer. NOTE: By default, the Windows installer will not add Rust to the %PATH% system variable. If this is the only version of Rust you are installing and you want to be able to run it from the command line, click on "Advanced" on the install dialog and on the "Product Features" page ensure "Add to PATH" is installed on the local hard drive.
If you decide you don't want Rust anymore, we'll be a bit sad, but that's okay. Not every programming language is great for everyone. Just run the uninstall script:
$ sudo /usr/local/lib/rustlib/uninstall.sh
If you used the Windows installer, just re-run the
.msi and it will give you
an uninstall option.
Some people, and somewhat rightfully so, get very upset when we tell you to
curl | sh. Basically, when you do this, you are trusting that the good
people who maintain Rust aren't going to hack your computer and do bad things.
That's a good instinct! If you're one of those people, please check out the
documentation on building Rust from Source, or the official
Oh, we should also mention the officially supported platforms:
We extensively test Rust on these platforms, and a few others, too, like Android. But these are the ones most likely to work, as they have the most testing.
Finally, a comment about Windows. Rust considers Windows to be a first-class platform upon release, but if we're honest, the Windows experience isn't as integrated as the Linux/OS X experience is. We're working on it! If anything does not work, it is a bug. Please let us know if that happens. Each and every commit is tested against Windows just like any other platform.
If you've got Rust installed, you can open up a shell, and type this:
$ rustc --version
You should see the version number, commit hash, and commit date. If you just installed version 1.2.0, you should see:
rustc 1.2.0 (082e47636 2015-08-03)
If you did, Rust has been installed successfully! Congrats!
If you didn't and you're on Windows, check that Rust is in your %PATH% system variable. If it isn't, run the installer again, select "Change" on the "Change, repair, or remove installation" page and ensure "Add to PATH" is installed on the local hard drive.
This installer also installs a copy of the documentation locally, so you can
read it offline. On UNIX systems,
/usr/local/share/doc/rust is the location.
On Windows, it's in a
share/doc directory, inside wherever you installed Rust
If not, there are a number of places where you can get help. The easiest is the #rust IRC channel on irc.mozilla.org, which you can access through Mibbit. Click that link, and you'll be chatting with other Rustaceans (a silly nickname we call ourselves), and we can help you out. Other great resources include the user’s forum, and Stack Overflow.
