Follow the instructions at If that doesn't work for you there are other installation methods.

rustup installs rustc, cargo, rustup and other standard tools to Cargo's bin directory. On Unix it is located at $HOME/.cargo/bin and on Windows at %USERPROFILE%\.cargo\bin. This is the same directory that cargo install will install Rust programs and Cargo plugins.

This directory will be in your $PATH environment variable, which means you can run them from the shell without further configuration. Open a new shell and type the following:

rustc --version

If you see something like rustc 1.19.0 (0ade33941 2017-07-17) then you are ready to Rust. If you decide Rust isn't your thing, you can completely remove it from your system by running rustup self uninstall.

Choosing where to install

rustup allows you to customise your installation by setting the environment variables CARGO_HOME and RUSTUP_HOME before running the rustup-init executable. As mentioned in the Environment Variables section, RUSTUP_HOME sets the root rustup folder, which is used for storing installed toolchains and configuration options. CARGO_HOME contains cache files used by cargo.

Note that you will need to ensure these environment variables are always set and that CARGO_HOME/bin is in the $PATH environment variable when using the toolchain.

Installing nightly

If you specify the nightly channel when installing rustup, the rustup-init script will do a "forced" installation by default. A "forced" installation means it will install the nightly channel regardless of whether it might be missing components that you want. If you want to install rustup with the nightly channel, and ensure it has the components that you want, you will need to do this in two phases. For example, if you want to make a fresh installation of rustup and then install nightly along with clippy or miri, first install rustup without a toolchain:

curl --proto '=https' --tlsv1.2 -sSf | sh -s -- --default-toolchain none -y

Next you can install nightly allowing rustup to downgrade until it finds the components you need:

rustup toolchain install nightly --allow-downgrade --profile minimal --component clippy

This can be used to great effect in CI, to get you a toolchain rapidly which meets your criteria.

Enable tab completion for Bash, Fish, Zsh, or PowerShell

rustup now supports generating completion scripts for Bash, Fish, Zsh, and PowerShell. See rustup help completions for full details, but the gist is as simple as using one of the following:

# Bash
$ rustup completions bash > ~/.local/share/bash-completion/completions/rustup

# Bash (macOS/Homebrew)
$ rustup completions bash > $(brew --prefix)/etc/bash_completion.d/rustup.bash-completion

# Fish
$ mkdir -p ~/.config/fish/completions
$ rustup completions fish > ~/.config/fish/completions/

# Zsh
$ rustup completions zsh > ~/.zfunc/_rustup

# PowerShell v5.0+
$ rustup completions powershell >> $PROFILE.CurrentUserCurrentHost
# or
$ rustup completions powershell | Out-String | Invoke-Expression

Note: you may need to restart your shell in order for the changes to take effect.

For zsh, you must then add the following line in your ~/.zshrc before compinit:
