How to install Solidity development on macOS in 2023

To set up a local environment for Solidity development on macOS, you will need to install the following tools:

Let’s do it step by step.

Install Homebrew

Homebrew is a package manager for macOS that makes it easy to install command-line tools. To install Homebrew, open a terminal window and run the following command:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install Node.js

Node.js is a JavaScript runtime that is required to run Solidity development tools such as Truffle. To install Node.js using Homebrew, run the following command:

brew install node

Install Truffle

Truffle is a popular development framework for Ethereum that simplifies the process of deploying and testing smart contracts. To install Truffle using npm (the Node.js package manager), run the following command:

npm install -g truffle

Install a Solidity compiler

To compile Solidity code, you will need to install a Solidity compiler such as solc. To install solc using npm, run the following command:

npm install -g solc

Install a local Ethereum blockchain

To test your smart contracts locally, you will need to set up a local Ethereum blockchain. One popular option is Ganache, which can be installed using npm:

npm install -g ganache-cli

Alternatively, you can use a local Ethereum client such as geth or Parity.

Conclusion

Once you have installed these tools, you should be ready to start developing Solidity smart contracts locally. You can use Truffle to compile, deploy, and test your contracts, and Ganache or a local Ethereum client to run a local blockchain.
