Installing Clarinet
What is Clarinet?
Clarinet is a Clarity runtime packaged as a command line tool, designed to facilitate smart contract understanding, development, testing and deployment. Clarinet consists of a Clarity REPL and a testing harness, which, when used together allow you to rapidly develop and test a Clarity smart contract, with the need to deploy the contract to a local devnet or testnet.
Clarity is a decidable smart contract language that optimises for predictability and security, designed for the Stacks blockchain. Smart contracts allow developers to encode essential business logic on a blockchain.
Install on macOS (Homebrew)
This process relies on the macOS package manager called Homebrew. Using the brew command you can easily add powerful functionality to your mac, but first we have to install it.
To get started, launch your Terminal (/Applications/Utilities/Terminal) application. Terminal is a versatile command line system that comes with every Mac computer.
If you do not already have XCode installed, it's best to first install the command line tools as these will be used by homebrew:
xcode-select --install
When the XCode is complete, proceed with Homebrew installation:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Now you can test your installation to ensure you have installed brew correctly, simply type:
% brew --version
Homebrew 3.6.3
Finally, you can now install the Clarinet on your mac:
brew install clarinet
Just follow the terminal prompts if necessary.
Install on Windows
The easiest way to install Clarinet on Windows is to use the MSI installer, that can be downloaded from the releases page.
Clarinet is also available on Winget, the package manager that Microsoft started including in the latest Windows updates:
winget install clarinet
Install from a pre-built binary
To install Clarinet from pre-built binaries, download the latest release from the releases page.
Unzip the binary, then copy it to a location that is already in your path, such as /usr/local/bin.
# note: you can change the v0.27.0 with version that are available in the releases page.
wget -nv https://github.com/hirosystems/clarinet/releases/download/v0.27.0/clarinet-linux-x64-glibc.tar.gz -O clarinet-linux-x64.tar.gz
tar -xf clarinet-linux-x64.tar.gz
chmod +x ./clarinet
mv ./clarinet /usr/local/bin
On MacOS, you may get security errors when trying to run the pre-compiled binary. You can resolve the security warning with this command:
xattr -d com.apple.quarantine /path/to/downloaded/clarinet/binary
Install from source using Cargo
Prerequisites
Install Rust for access to cargo, the Rust package manager.
On Debian and Ubuntu-based distributions, please install the following packages before building Clarinet.
sudo apt install build-essential pkg-config libssl-dev
Build Clarinet
You can build Clarinet from source using Cargo with the following commands:
git clone https://github.com/hirosystems/clarinet.git --recursive
cd clarinet
cargo clarinet-install
By default, you will be in our development branch, develop, with code that has not been released yet. If you plan to submit any changes to the code, then this is the right branch for you. If you just want the latest stable version, switch to the main branch:
git checkout main
If you have previously checked out the source, ensure you have the latest code (including submodules) before building using:
git pull
git submodule update --recursive
Verify Clarinet installation
You can verify Clarinet is installed properly by running clarinet --version in
your favourite Terminal emulator.
% clarinet --version
clarinet-cli 1.0.2
