455455### Install with npm
456 
457> [!NOTE]
458>
459> If `npm --version` prints a version starting with `12` in your shell, follow [Fix an npm 12 install](https://code.claude.com/docs/en/troubleshoot-install.md#fix-an-npm-12-install) instead. Don't install with `sudo`. Claude Code runs npm without `sudo` when it updates itself, so an install that needs `sudo` can't update automatically.

457461You can also install Claude Code as a global npm package. The npm package requires [Node.js 22 or later](https://nodejs.org/en/download). On an older Node.js version, npm prints an `EBADENGINE` warning during install rather than failing; the install completes and `claude` still runs, since the package downloads a native binary that doesn't use your Node.js at runtime.
