Node.js
OpenClaw requires Node 22 or newer. The installer script 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
node -vIf 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
macOS
Homebrew (recommended):
brew install nodeOr download the macOS installer from nodejs.org.
Linux
Ubuntu / Debian:
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt-get install -y nodejsFedora / RHEL:
sudo dnf install nodejsOr use a version manager (see below).
Windows
winget (recommended):
winget install OpenJS.NodeJS.LTSChocolatey:
choco install nodejs-ltsOr download the Windows installer from nodejs.org.
Using a version manager (nvm, fnm, mise, asdf)
Version managers let you switch between Node versions easily. Popular options:
- fnm — fast, cross-platform
- nvm — widely used on macOS/Linux
- mise — polyglot (Node, Python, Ruby, etc.)
Example with fnm:
fnm install 22
fnm use 22Warning: Make sure your version manager is initialized in your shell startup file (
~/.zshrcor~/.bashrc). If it isn’t,openclawmay 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.
Find your global npm prefix
npm prefix -gCheck if it’s on your PATH
echo "$PATH"Look for <npm-prefix>/bin (macOS/Linux) or <npm-prefix> (Windows) in the output.
Add it to your shell startup file
macOS / Linux
Add to ~/.zshrc or ~/.bashrc:
export PATH="$(npm prefix -g)/bin:$PATH"Then open a new terminal (or run rehash in zsh / hash -r in bash).
Windows
Add the output of npm prefix -g to your system PATH via Settings → System → Environment Variables.
Permission errors on npm install -g (Linux)
If you see EACCES errors, switch npm’s global prefix to a user-writable directory:
mkdir -p "$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.
