% Installing Rust
|
||
|
||
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.
|
||
|
||
```bash
|
||
$ curl -sf -L https://static.rust-lang.org/rustup.sh | sh
|
||
```
|
||
|
||
If you're concerned about the [potential insecurity][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:
|
||
|
||
```bash
|
||
$ curl -f -L https://static.rust-lang.org/rustup.sh -O
|
||
$ sh rustup.sh
|
||
```
|
||
|
||

|
||
|
||
If you're on Windows, please download the appropriate [installer][install-page].
|
||
**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.

||

||

|
||
|
||
## Uninstalling
|
||
|
||
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:
|
||
|
||
```bash
|
||
$ 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.
|
||
|
||
## That disclaimer we promised
|
||
|
||
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][from-source], or [the official
|
||
binary downloads][install-page].
|
||
|
||

|
||
|
||
## Platform support
|
||
|
||
Oh, we should also mention the officially supported platforms:
|
||
|
||
* Windows (7, 8, Server 2008 R2)
|
||
* Linux (2.6.18 or later, various distributions), x86 and x86-64
|
||
* OSX 10.7 (Lion) or later, x86 and x86-64
|
||
|
||
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.
|
||
|
||
## After installation
|
||
|
||
If you've got Rust installed, you can open up a shell, and type this:
|
||
|
||
```bash
|
||
$ rustc --version
|
||
```
|
||
|
||
You should see the version number, commit hash, and commit date. If you just
|
||
installed version 1.2.0, you should see:
|
||
|
||
```bash
|
||
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
|
||
to.
|
||
|
||
If not, there are a number of places where you can get help. The easiest is
|
||
[the #rust IRC channel on irc.mozilla.org][irc], which you can access through
|
||
[Mibbit][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][users], and
|
||
[Stack Overflow][stackoverflow].
