Run node -v: if it reports 20.x or 22+, jump to Install Even Hub tooling. Otherwise, start here.Target version: Node 20 LTS or 22+. The SDK declares engines.node = "^20.0.0 || >=22.0.0". Node 18 is not supported. ## macOS - Homebrew ​ First install Homebrew if you don't have it:bash ``` /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" ``` Then:bash ``` brew install node@22 ``` ## Windows - official installer ​ Download the LTS installer from nodejs.org and run it. Accept the option to add Node to PATH. ## Linux - NodeSource ​ Distro packages are often outdated. Prefer NodeSource:bash ``` curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash - sudo apt-get install -y nodejs ``` Prefer a version manager? (fnm / nvm / winget)A version manager lets you switch Node versions per project and avoids global-permission headaches.macOS / Linux - fnm or nvmbash ``` # fnm (fast) curl -fsSL https://fnm.vercel.app/install | bash # restart your shell, then: fnm install 22 fnm use 22 # or nvm curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash nvm install 22 nvm use 22 ``` Windows - fnm or wingetpowershell ``` # winget (ships with Windows 10/11) winget install OpenJS.NodeJS.LTS # or fnm via winget, then: fnm install 22 fnm use 22 ``` ## Verify ​ bash ``` node -v # v20.x or v22.x+ npm -v ``` ## Common gotchas ​ macOS - PATH after Homebrew. On Apple Silicon, Homebrew installs to /opt/homebrew. If node isn't found after install, ensure your shell profile sources it:bash ``` echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile exec zsh ``` Windows - shimmed node.exe. Version managers (fnm/nvm-windows) expose node through a shim. This matters later: Windows Defender may block the shimmed node.exe inbound without prompting - see Hardware → Network & Firewall Setup.Linux/macOS - EACCES on global installs. If npm install -g fails with EACCES, do not sudo npm. Use a version manager (which installs into your home dir), or set a user-owned npm prefix:bash ``` npm config set prefix "$HOME/.npm-global" export PATH="$HOME/.npm-global/bin:$PATH" # add to your shell profile ``` No global install? Use npx. The CLI runs without a global install:bash ``` npx @evenrealities/evenhub-cli qr --url "http://:5173" ``` Handy on locked-down machines. A global install is faster for repeated use.PagerPrevious pageHardwareNext pageInstall Even Hub tooling
