--- title: "Node.js + npm (PATH sanity)" summary: "Node.js + npm install sanity: versions, PATH, and global installs" read_when: - "You installed Clawdbot but `clawdbot` is “command not found”" - "You’re setting up Node.js/npm on a new machine" - "npm install -g ... fails with permissions or PATH issues" --- # Node.js + npm (PATH sanity) Clawdbot’s runtime baseline is **Node 22+**. If you can run `npm install -g clawdbot@latest` but later see `clawdbot: command not found`, it’s almost always a **PATH** issue: the directory where npm puts global binaries isn’t on your shell’s PATH. ## Quick diagnosis Run: ```bash node -v npm -v npm prefix -g echo "$PATH" ``` If `$(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 `clawdbot`). ## Fix: put npm’s global bin dir on PATH 1) Find your global npm prefix: ```bash npm prefix -g ``` 2) Add the global npm bin directory to your shell startup file: - zsh: `~/.zshrc` - bash: `~/.bashrc` Example (replace the path with your `npm prefix -g` output): ```bash # macOS / Linux export PATH="/path/from/npm/prefix/bin:$PATH" ``` Then open a **new terminal** (or run `rehash` in zsh / `hash -r` in bash). On Windows, add the output of `npm prefix -g` to your PATH. ## Fix: avoid `sudo npm install -g` / permission errors (Linux) If `npm install -g ...` fails with `EACCES`, switch npm’s global prefix to a user-writable directory: ```bash mkdir -p "$HOME/.npm-global" npm config set prefix "$HOME/.npm-global" export PATH="$HOME/.npm-global/bin:$PATH" ``` Persist the `export PATH=...` line in your shell startup file. ## Recommended Node install options You’ll have the fewest surprises if Node/npm are installed in a way that: - keeps Node updated (22+) - makes the global npm bin dir stable and on PATH in new shells Common choices: - 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.
