--- title: "Node.js" summary: "Install and configure Node.js for OpenClaw — version requirements, install options, and PATH troubleshooting" read_when: - "You need to install Node.js before installing OpenClaw" - "You installed OpenClaw but `openclaw` is command not found" - "npm install -g fails with permissions or PATH issues" --- # Node.js OpenClaw requires **Node 22 or newer**. The [installer script](/install#install-methods) will detect and install Node automatically — this page is for when you want to set up Node yourself and make sure everything is wired up correctly (versions, PATH, global installs). ## Check your version ```bash node -v ``` If this prints `v22.x.x` or higher, you're good. If Node isn't installed or the version is too old, pick an install method below. ## Install Node **Homebrew** (recommended): ```bash brew install node ``` Or download the macOS installer from [nodejs.org](https://nodejs.org/). **Ubuntu / Debian:** ```bash curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash - sudo apt-get install -y nodejs ``` **Fedora / RHEL:** ```bash sudo dnf install nodejs ``` Or use a version manager (see below). **winget** (recommended): ```powershell winget install OpenJS.NodeJS.LTS ``` **Chocolatey:** ```powershell choco install nodejs-lts ``` Or download the Windows installer from [nodejs.org](https://nodejs.org/). Version managers let you switch between Node versions easily. Popular options: - [**fnm**](https://github.com/Schniz/fnm) — fast, cross-platform - [**nvm**](https://github.com/nvm-sh/nvm) — widely used on macOS/Linux - [**mise**](https://mise.jdx.dev/) — polyglot (Node, Python, Ruby, etc.) Example with fnm: ```bash fnm install 22 fnm use 22 ``` Make sure your version manager is initialized in your shell startup file (`~/.zshrc` or `~/.bashrc`). If it isn't, `openclaw` may not be found in new terminal sessions because the PATH won't include Node's bin directory. ## Troubleshooting ### `openclaw: command not found` This almost always means npm's global bin directory isn't on your PATH. ```bash npm prefix -g ``` ```bash echo "$PATH" ``` Look for `/bin` (macOS/Linux) or `` (Windows) in the output. Add to `~/.zshrc` or `~/.bashrc`: ```bash export PATH="$(npm prefix -g)/bin:$PATH" ``` Then open a new terminal (or run `rehash` in zsh / `hash -r` in bash). Add the output of `npm prefix -g` to your system PATH via Settings → System → Environment Variables. ### Permission errors on `npm install -g` (Linux) If you see `EACCES` errors, switch npm's global prefix to a user-writable directory: ```bash mkdir -p "$HOME/.npm-global" npm config set prefix "$HOME/.npm-global" export PATH="$HOME/.npm-global/bin:$PATH" ``` Add the `export PATH=...` line to your `~/.bashrc` or `~/.zshrc` to make it permanent.
