Install the Scrypto Toolchain

To begin working with Scrypto, you need to prepare your system for Rust development, and then install the Scrypto libraries, simulator, commandline tools from the Scrypto GitHub repo.

Install Rust compiler
- On Windows:
  - Install "Desktop development with C++" with Build Tools for Visual Studio 2019
  - Download and install rustup-init.exe
- On Linux or macOS:
  - Make sure a C++ compiler is installed (sudo apt install build-essential with Ubuntu)
  - Install Rust compiler
    
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Enable cargo in the current shell:
- On Windows:
  - Start a new PowerShell
- On Linux or macOS:
  source $HOME/.cargo/env

Add WebAssembly target:

rustup target add wasm32-unknown-unknown

Install simulator and command-line tools:

git clone https://github.com/radixdlt/radixdlt-scrypto.git
cd radixdlt-scrypto
cargo install --path ./simulator

If you encounter problems when installing the simulator, make sure that you’re running the latest stable version of Rust before trying again!
