node -v- What it does
- Shows the Node.js version on this computer before you install or update OpenClaw.
- When to use it
- Use it first when the install guide asks for Node.js, or when you are not sure whether this machine already has Node installed.
- What happens next
- The terminal prints a version like `v20.x`. If Node is missing, the shell tells you the command cannot be found.
- Risk note
- Safe. It only reads local tool information and does not change anything.
