Article Summary

Here you'll find steps for installing the Scrypto toolchain on Linux, macOS and Windows. Troubleshooting suggestions follow after the installation instructions.

Install the Scrypto Toolchain

To begin working with Scrypto, you need to first prepare you system for Rust development. Then you can install the Scrypto Libraries, Radix Engine Simulator (resim) and command line tools from the Radixdlt-Scrypto github repository.

1. Install Rust compiler

On Windows:

On macOS:

  • Make sure you have the xcode command line tools by running:
xcode-select --install
  • Install cmake and LLVM
brew install cmake llvm
  • Check, which shell is the default one by inspecting $SHELL variable:
echo $SHELL
  • Add LLVM to the system path by adding below line to the ~/.profile or ~/.zshrc
PATH="$(brew --prefix llvm)/bin:$PATH"
  • ~/.profile if bash is the default shell

  • ~/.zshrc if zsh is the default shell

  • respective config file in case of other shell

  • Install Rust compiler
curl --proto '=https' --tlsv1.2 -sSf | sh

On Linux:

  • Make sure a C++ compiler and LLVM is installed:
sudo apt install clang build-essential llvm
  • Install Rust compiler
curl --proto '=https' --tlsv1.2 -sSf | sh

2. Enable cargo in the current shell

On Windows:

  • Start a new PowerShell

On macOS or Linux:

source $HOME/.cargo/env

3. Add WebAssembly target

On Windows, macOS or Linux:

rustup target add wasm32-unknown-unknown

4. Install Radix Engine Simulator and command-line tools

On Windows, macOS or Linux:

cargo install --force radix-clis

When you install the simulator crate you get two things, the scrypto CLI tool which is essentially a wrapper around the cargo CLI tool with a few adjustments and resim the Radix Engine Simulator


Have an x86 (Intel-based) MacOS? Try the following steps:

  • Define rust stable:
rustup default 1.77.2
  • Install LLVM@15 using brew:
brew install llvm@15
  • Confirm the Installation Path:
brew --prefix llvm@15

Output: /usr/local/opt/llvm@15

  • Add LLVM to the system path by adding below line to the ~/.zshrc
PATH="$(brew --prefix llvm@15)/bin:$PATH"
  • Reload the environment:
source ~/.zshrc
  • Check that the installation of LLVM was done correctly by checking the clang version
clang --version


Homebrew clang version 15.0.7
Target: x86_64-apple-darwin23.4.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm@15/bin
  • Install XCode from the App Store

  • Reset the XCode config:

xcodebuild -runFirstLaunch
