How to Install Codex CLI on Windows 11
In this step-by-step tutorial, you’ll learn how to install and use Codex CLI on Windows 11. This guide will help you set up a powerful AI coding assistant directly in your terminal so you can generate code, debug issues, and automate development tasks efficiently.
Codex CLI is an open-source tool that brings AI-powered coding directly to your command line, allowing you to interact with your codebase using natural language. ([OpenAI Help Center][1])
⚠️ Important Note:
Codex CLI does not fully support native Windows yet — the recommended method is to use WSL (Windows Subsystem for Linux) for the best experience. ([Mintlify][2])

### 🧠 What You’ll Learn in This Video:
• How to install WSL2 on Windows 11
• Setting up Ubuntu (Linux environment)
• Installing Node.js inside WSL
• Installing Codex CLI globally using npm
• Setting up your OpenAI API key
• Running your first Codex CLI command
• Using Codex for coding, debugging, and automation
• Fixing common installation issues
---
### ⚙️ Step-by-Step Overview:
1. Install WSL (Recommended Method)
Open PowerShell (Admin) and run:
```
wsl --install
```
Restart your system after installation.
2. Open Ubuntu (WSL Terminal)
Launch Ubuntu from Start Menu.
3. Install Node.js (inside WSL)
```
sudo apt update
sudo apt install -y nodejs npm
```
4. Install Codex CLI
```

### 💡 Alternative (Native Windows – Experimental)
You can install directly in PowerShell:
```
npm install -g @openai/codex
```
But this method may have limitations and is not fully stable yet. ([ITECS][3])
