OpenClaw requires **Node 22.22.3+, Node 24.15+, or Node 25.9+** (which includes Node 26). **Node 26 is the default and recommended runtime** — it starts the Gateway noticeably faster and uses less memory than Node 24, and the installer script provisions it when Node is missing. CI and release workflows still pin Node 24; Node 22 remains supported via its LTS line. Node 23 is unsupported. The [installer script](/install#alternative-install-methods) detects and installs Node automatically — use this page when you want to set up Node yourself (versions, PATH, global installs).

## Check your version

```bash
node -v
```

`v26` (any release) is the recommended default. `v24.15.0` or newer 24.x remains fully supported (and is what CI pins); `v22.22.3` or newer 22.x is the supported Node 22 LTS path; Node `v25.9.0+` is also supported. Node 23 is unsupported. If Node is missing or outside the supported range, pick an install method below.

## Install Node

<Tabs>
  <Tab title="macOS">
    **Homebrew** (recommended):

    ```bash
    brew install node
    ```

    Or download the macOS installer from [nodejs.org](https://nodejs.org/).

  </Tab>
  <Tab title="Linux">
    **Ubuntu / Debian:**

    ```bash
    curl -fsSL https://deb.nodesource.com/setup_26.x | sudo -E bash -
    sudo apt-get install -y nodejs
    ```

    **Fedora / RHEL:**

    ```bash
    sudo dnf install nodejs
    ```

    Or use a version manager (see below).

  </Tab>
  <Tab title="Windows">
    **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/).

  </Tab>
</Tabs>

<Accordion title="Using a version manager (nvm, fnm, mise, asdf)">
  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 26
fnm use 26
```

  <Warning>
  Initialize your version manager in your shell startup file (`~/.zshrc` or `~/.bashrc`). If you skip this, `openclaw` may not be found in new terminal sessions because PATH won't include Node's bin directory.
  </Warning>
</Accordion>

## Troubleshooting

### `openclaw: command not found`

This almost always means npm's global bin directory isn't on your PATH.

<Steps>
  <Step title="Find your global npm prefix">
    ```bash
    npm prefix -g
    ```
  </Step>
  <Step title="Check if it's on your PATH">
    ```bash
    echo "$PATH"
    ```

    Look for `<npm-prefix>/bin` (macOS/Linux) or `<npm-prefix>` (Windows) in the output.

  </Step>
  <Step title="Add it to your shell startup file">
    <Tabs>
      <Tab title="macOS / Linux">
        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).
      </Tab>
      <Tab title="Windows">
        Add the output of `npm prefix -g` to your system PATH via Settings → System → Environment Variables.
      </Tab>
    </Tabs>

  </Step>
</Steps>

### 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.
