LovetekiMac:/ love$ error: Appium will not work if used or installed with sudo. Please rerun/install as a non-root user. If you had to install Appium using sudo npm install -g appium, the solution is to reinstall Node using a method (Homebrew, for example) that doesn't require sudo to install global npm packages.
