You can check the versions of npm,node and node-red using: npm -v Note: npm install failed on my pi and I had to use this command first: sudo apt-get install -y build-essential This you can do using: sudo apt-get update You may need to upgrade node-red which you can do by doing an install using npm but you will need to install npm first. Node red is already installed on Raspberry pi but npm (node package manager) isn’t. Using the -g option adds the node-red command to your path. Then you can Install node red on Windows and Linux (including raspberry pi) using:
Installing Node on Linux Using a Package Manager.Node-Red is a node application and before you Install node red you will need to first install node.
