Prerequisites for Running Understand Anything: Node.js and pnpm Setup Guide

To run Understand Anything, you must install Node.js version 22 or higher and pnpm version 10 or higher.

Understand Anything is a monorepo project that relies on modern JavaScript tooling to manage its workspace dependencies and build pipeline. Before cloning the repository or installing dependencies, you need to configure your local environment with specific versions of Node.js and pnpm as specified in the project's configuration files.

Core System Requirements

The foundation of the Understand Anything workflow rests on two essential tools that work in lock-step to provide the JavaScript runtime and package management capabilities.

Node.js Version 22 or Higher

Node.js provides the JavaScript runtime environment required to execute the application code. According to the CLAUDE.md documentation in the repository root, the project requires Node.js version 22 or higher, though development actively targets version 24.

pnpm Version 10 or Higher

pnpm serves as the mandatory package manager for this monorepo workspace. The root package.json explicitly pins the required version through the packageManager field, specifying pnpm@>=10. This ensures consistent dependency resolution across all workspace packages.

Verifying Your Installation

Before proceeding with repository setup, confirm your tooling meets the minimum requirements by running the following commands in your terminal.

Check Node.js Version

# Should print a version ≥ 22

node --version

Check pnpm Version

# Should print a version ≥ 10

pnpm --version

Installation Methods

If either prerequisite is missing or outdated, use one of the following approaches to install the required tools.

Automated Installation (macOS/Linux)

For Unix-based systems, the repository provides a convenience script that checks for and installs the required dependencies:

curl -fsSL https://raw.githubusercontent.com/Lum1104/Understand-Anything/main/install.sh | bash

The script automatically detects missing versions of Node.js or pnpm and prompts you to install them before continuing.

Manual pnpm Upgrade

If you need to upgrade pnpm to meet the version 10 requirement, install the latest version globally:

npm i -g pnpm@latest

Key Configuration Files

Several files in the repository root enforce and document these prerequisites.

• package.json: Declares the required packageManager (pnpm@>=10) and lists core dependencies for the workspace.
• pnpm-workspace.yaml: Defines the monorepo layout that pnpm reads to resolve packages across the workspace.
• CLAUDE.md: Contains the official "Prerequisites" section documenting the Node.js ≥ 22 and pnpm ≥ 10 requirements.

Summary

• Understand Anything requires Node.js ≥ 22 and pnpm ≥ 10 to function correctly.
• The packageManager field in package.json enforces the pnpm version requirement.
• Run node --version and pnpm --version to verify your environment before cloning.
• Use the provided install.sh script on macOS/Linux for automated setup.
• Configuration files in the repository root document and enforce these requirements.

Frequently Asked Questions

Can I use npm or yarn instead of pnpm?

No. The Understand Anything monorepo requires pnpm specifically. The root package.json contains a packageManager field that pins pnpm version 10 or higher, and the pnpm-workspace.yaml file defines the workspace structure that only pnpm can interpret correctly.

What happens if I try to run the project with Node.js 20?

You may encounter compatibility issues or runtime errors. The project is developed on Node.js version 24 and requires features available only in Node.js 22 and higher. Always verify your version with node --version before installation.

Does the automated installation script work on Windows?

The install.sh script provided in the repository root works specifically on macOS and Linux systems. Windows users should install Node.js and pnpm manually or use Windows Subsystem for Linux (WSL) to run the shell script.

Where are the prerequisites officially documented?

The prerequisites are officially documented in the CLAUDE.md file located in the repository root. This file specifies Node.js ≥ 22 and pnpm ≥ 10 as the minimum versions required to run the project.
