The Sway toolchain is sufficient to compile Sway smart contracts. Otherwise, note that if you want to run Sway smart contracts (e.g. for testing), a Fuel Core full node is required, which is packaged together with the Sway toolchain together as the Fuel toolchain.
Installing via pre-compiled release binaries is the recommended way to get up and running with the Sway toolchain. Pre-compiled binaries for Linux and macOS are available. Native Windows is currently unsupported (tracking issue for Windows support ). Windows Subsystem for Linux should work but is not officially supported.
A prerequisite for installing and using Sway is the Rust toolchain. Platform-specific instructions for installing rustup can be found here . Then, install the Rust toolchain with:
# Install the latest stable Rust toolchain.
rustup install stable The Sway toolchain is built and tested against the stable Rust toolchain version (https://github.com/rust-lang/rust/releases/latest ). There is no guarantee it will work with the nightly Rust toolchain, or with earlier stable versions, so ensure you are using stable with:
# Update installed Rust toolchain; can be used independently.
rustup update
# Set the stable Rust toolchain as default; can be used independently.
rustup default stable Now you're ready to install fuelup , the equivalent of Rust's rustup for the Fuel toolchain. It enables easily downloading binary releases of the Fuel toolchain.
Start by installing fuelup with the following command:
curl --proto '=https' --tlsv1.2 -sSf \
https://install.fuel.network/fuelup-init.sh | sh This downloads the fuelup-init script to a temp directory on your machine, which installs fuelup. fuelup-init will ask for permission to add ~/.fuelup/bin to your PATH. Otherwise, you can also pass --no-modify-path so that fuelup-init does not modify your PATH:
curl --proto '=https' --tlsv1.2 -sSf \
https://install.fuel.network/fuelup-init.sh | sh -s -- --no-modify-path Once fuelup is installed, fuelup-init automatically runs fuelup toolchain install latest to install the latest toolchain
You can run fuelup update at anytime to get the most up-to-date toolchain.
(Optional) You can optionally install distributed toolchains optimized for different networks.
To configure the optimal toolchain for beta-3, run the following commands:
$ fuelup self update

The Fuel toolchain is installed and up to dateYou're all set to start building!
You may refer to The Fuelup Book for an in-depth look into fuelup, or check out the tooling section in the Fuel forum if you're running into problems through the installation process. If you don't see your question, post the issue you're running into with as many details as possible and the team will get back to you asap!
The Sway toolchain and Fuel Core full node can be installed from source with Cargo with:
cargo install forc fuel-coreforc from Cargo You can update the toolchain from source with Cargo with:
cargo update forc fuel-coreforc Plugins from Cargo The Fuel ecosystem has a few plugins which can be easily installed via Cargo.
Note:
forcdetects anything in your$PATHprefixed withforc-as a plugin. Useforc pluginsto see what you currently have installed.
# Sway Formatter
cargo install forc-fmt
# Block Explorer
cargo install forc-explore
# Sway Language Server
cargo install forc-lsp Rather than installing from cargo, the Sway toolchain can be built from a local source checkout by following instructions at https://github.com/FuelLabs/sway . The Fuel Core full node implementation can be built from source by following instructions at https://github.com/FuelLabs/fuel-core .
forc supports generating completion scripts for Bash, Fish, Zsh, and PowerShell. See forc completions --help for full details, but the gist is as simple as using one of the following:
# Bash
forc completions --shell=bash > ~/.local/share/bash-completion/completions/forc
# Bash (macOS/Homebrew)
forc completions --shell=bash > $(brew --prefix)/etc/bash_completion.d/forc.bash-completion
# Fish
mkdir -p ~/.config/fish/completions
forc completions --shell=fish > ~/.config/fish/completions/forc.fish
# Zsh
forc completions --shell=zsh > ~/.zfunc/_forc
# PowerShell v5.0+
forc completions --shell=powershell >> $PROFILE.CurrentUserCurrentHost
# or
forc completions --shell=powershell | Out-String | Invoke-ExpressionOnce the completions have been generated and properly installed, close and reopen your terminal for the new completions to take effect.
