If you can run `npm install -g openclaw@latest` but later see `openclaw: command not found`, it’s almost always a **PATH** issue: the directory where npm puts global binaries isn’t on your shell’s PATH.
If `$(npm prefix -g)/bin` (macOS/Linux) or `$(npm prefix -g)` (Windows) is **not** present inside `echo "$PATH"`, your shell can’t find global npm binaries (including `openclaw`).
- macOS: Homebrew (`brew install node`) or a version manager
- Linux: your preferred version manager, or a distro-supported install that provides Node 22+
- Windows: official Node installer, `winget`, or a Windows Node version manager
If you use a version manager (nvm/fnm/asdf/etc), ensure it’s initialized in the shell you use day-to-day (zsh vs bash) so the PATH it sets is present when you run installers.
