## Why The Codex JavaScript shim currently distinguishes npm and Bun installs, but a global pnpm install falls back to npm. That causes the native CLI, `codex doctor`, and update flows to report or run npm commands even though pnpm owns the installation. pnpm also allows its global package and bin directories to differ, so `PNPM_HOME` does not reliably identify the package owner. ## What changed - detect pnpm-managed installs by finding pnpm's `node_modules/.modules.yaml` metadata from the launched JavaScript entrypoint - pass a mutually exclusive `CODEX_MANAGED_BY_PNPM` marker into the native CLI - represent pnpm in install context, doctor output, version checks, and TUI update actions without changing the existing public `InstallContext::from_exe` signature - recommend `pnpm add -g @openai/codex` for pnpm-managed installs and snapshot the rendered TUI update notice Validated with the 9-test install-context suite, the focused pnpm TUI snapshot test, and Node's syntax check for the launcher. Closes https://github.com/openai/codex/issues/10294.
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
