Development Setup Guide
The Complete Setup Guide for a Chainlink Development Environment
Install Go, Git, developer tools, Python (2.7), curl
Debian-based Linux (Ubuntu, Mint, etc.)
sudo apt install -y git build-essential python curl
Red Hat-based Linux (CentOS, Fedora, etc.)
sudo yum groupinstall -y 'C Development Tools and Libraries' sudo yum install -y git python curl
brew install git curl golang
Windows-based environments can follow the instructions here.
After this point, instructions should be general for any *nix flavored operating system.
npm install -g yarn
Go (if not previously installed)Download
If needed, adjust the location of your Go installation and
.bashrc to your setup.
mkdir ~/go export GOPATH=~/go export PATH=$PATH:/usr/local/go/bin:~/go/bin echo "GOPATH=$GOPATH" >> ~/.bashrc echo "PATH=$PATH" >> ~/.bashrc source ~/.bashrc
Download Chainlink and install dependencies
git clone firstname.lastname@example.org:smartcontractkit/chainlink.git cd chainlink make install
The first time running
make install will take a while to finish.
Once complete, you can run
chainlink -h to check that the binary was created.
For local development, tools are available in the
cldev: sets environment variables and runs the source of the node directly
gethnet: (requires Geth to be installed) runs a local Geth Ethereum instance
devnet: (requires Docker to be installed) runs a local Parity Ethereum instance
Working with contracts
cd evm yarn install yarn test
