How to Install Solidity: A Complete Guide for Beginners (2025)

Ready to build smart contracts on the Ethereum blockchain? The first tool you need is the Solidity compiler, often called solc. This program turns your human-readable Solidity code into bytecode that the Ethereum Virtual Machine (EVM) can understand.

This guide will walk you through the most common and effective ways to install it. For any real project you plan to deploy, always use the latest stable version.

The Easiest Start: Remix IDE 🚀

If you're new to Solidity or working on small contracts, the easiest way to start is with Remix.

Remix is a powerful, web-based IDE that runs entirely in your browser. It comes with the Solidity compiler built-in, so you don't need to install anything on your computer. It's the perfect tool for learning, writing, and testing contracts quickly.

Installing the Command-Line Compiler

For larger projects or more advanced development workflows, you'll want to install the command-line compiler on your computer. Here are the most popular methods.

Using npm (For JavaScript Developers)

If you're already working with Node.js and npm, this is a very convenient option. This method installs solcjs, a JavaScript version of the Solidity compiler. 

npm install --global solc

Using Docker (For a Clean, Isolated Setup)

Docker lets you run applications in isolated "containers," which avoids conflicts with other software. To run the latest stable compiler version, use this command: 

docker run ethereum/solc:stable --version

Using Package Managers (Linux & macOS)

For Linux or macOS, using a package manager is often the simplest approach.

For Ubuntu/Debian, use these commands: 

sudo add-apt-repository ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install solc

For macOS with Homebrew, run this: 

brew update
brew tap ethereum/ethereum
brew install solidity

Verifying Your Installation ✅

Once installed, you can verify that everything is working correctly by opening your terminal and checking the version. 

solc --version

If you installed it via npm, use solcjs --version instead. If the command returns a version number, you're all set!

How to Easily Install Rust on WSL (Ubuntu 24.04)

-
Do you want to start programming with Rust? Rust is a modern programming language known for being fast, safe, and reliable. If you are a Windows user, a great way to develop with Rust is by using the Windows Subsystem for Linux (WSL). This guide will show you the simple steps to install Rust on your computer using WSL, specifically with the new Ubuntu 24.04. Step 1: Get Your System Ready Before we install Rust, we need to make sure our Ubuntu environment has the necessary tools. Rust depends on a C compiler and other build utilities. First, open your WSL Ubuntu 24.04 terminal. Then, run the following command to update your system's package lists: sudo apt update && sudo apt upgrade -y Next, install the build-essential package. This package includes the GCC compiler and other tools that Rust needs to work correctly. sudo apt install build-essential -y Now your system is ready for Rust! Step 2: Install Rust with rustup ...

Introduction This guide shows you step-by-step how to install Ubuntu 24.04 LTS using WSL (Windows Subsystem for Linux) on Windows 10 or Windows 11. It's a great solution to run Linux without dual boot or virtual machines. Requirements Windows 10 (version 2004 or later) or Windows 11 Internet connection Administrator access 1. Enable WSL Open PowerShell as administrator and run this command: wsl --install This command enables the necessary features, installs the WSL platform, and downloads Ubuntu (usually the latest stable version). 2. Install Ubuntu 24.04 Manually (if needed) If you want to install Ubuntu 24.04 specifically, you can do it manually: wsl --install -d Ubuntu-24.04 Or if WSL is already installed: wsl --list --online wsl --install -d Ubuntu-24.04 3. First Launch and Setup After installation, open Ubuntu from the Start Menu. The first time you launch it, y...

Getting Started with Rust: A Beginner’s Guide Getting Started with Rust: A Beginner’s Guide Published on July 20, 2025 Setting Up the Workspace First, we need to establish a directory to store our code. While Rust is indifferent to its location, it is good practice to keep your projects well-organized. Open a terminal (or command prompt) and create a directory for your project. For Linux, macOS, and PowerShell (on Windows): # Create a "projects" directory in your home directory mkdir ~/projects # Enter the newly created directory cd ~/projects # Create the directory for our specific project mkdir hello_world # Enter the project directory cd hello_world For the Windows Command Prompt (CMD): > mkdir "%USERPROFILE%\projects" > cd /d "%USERPROFILE%\projects" > mkdir hello_world > cd hello_world Writing and Executing the P...
