Uninstall Node.js # If for some reasons you want to uninstall Node.js package, you can use the following command: sudo apt remove nodejs Conclusion # We have shown you two different ways to install Node.js and npm on your Raspberry Pi board. The method you choose depends on your requirements and preferences. Even though installing the packaged version from the NodeSource repository is easier, the nvm method gives you more flexibility for adding and removing different Node.js. To uninstall node I followed the accepted answer by @George, as I no longer have the sources, but before doing so I ran: sudo npm rm npm -g That seemed to get rid of npm from the system directories such as /usr/bin/npm and /usr/lib/npm. I got the command from here To confirm that npm uninstall worked correctly, check that the node_modules directory no longer contains a directory for the uninstalled package(s). Unix system (such as OSX): ls node_modules; Windows systems: dir node_modules; Uninstalling global packages. To uninstall an unscoped global package, on the command line, use the uninstall command with the -g flag. Include the scope if the package. In this short tutorial we will go through how to install NodeJS and the Node Package Manager (NPM) on the Raspberry Pi. Step 1: Update & Upgrade your Pi To prevent any issues with compatibility, always update the dependencies list on the Raspberry Pi and upgrade the libraries on the Pi before installing new libraries. Run the following commands in the terminal. sudo apt-get update This command updates the list of packages that can be installed, and checks if currently installed. npm uninstall node-red-dashboard Install, disable, uninstall, modules from the Palette Manager From the WEB interface, open the menu and select Manage Palette. The Manager opens to the left of the screen instead of the pallets
Run the following commands in your pi's terminal to remove any old installs of Node.js and npm - sudo apt remove nodered -y sudo apt remove node nodejs nodejs-legacy -y sudo apt remove npm -y. If you now run the node -v or npm -v commands you should get a command not found error. Once that's set we're going to run: sudo apt remove --purge node. The purge flag is like the remove command, except it also removes any configuration or data files that remove may have left behind Then go about removing nodejs. I would start with sudo apt purge nodejs - then got into /usr/local/bin and remove node and npm if still there - and then do likewise in /usr/bin. Then go into /etc/sources.list.d and remove nodesource.list if it exists.. Um npm und nodejs auf den Raspberry zu bekommen, hilft dieser Befehl: sudo apt-get install nodejs npm As with running Node-RED locally, you can use the node-red command to run Node-RED in a terminal. It can then be stopped by pressing Ctrl-C or by closing the terminal window. Due to the limited memory of the Raspberry Pi, you will need to start Node-RED with an additional argument to tell the underlying Node.js process to free up unused memory sooner than it would otherwise Select Yes to reboot the Raspberry Pi. You can now unplug the monitor and keyboard from the Raspberry Pi, and we can log in using out SSH client. Open PuTTY, type in the IP address for your Raspberry Pi, and click Open: Log in using the username pi and the new password you specified
Finally, if you are not using PulseAudio for anything other than Bluetooth audio, remove it from the image by entering: sudo apt -y purge pulseaudio* If moving to a new Pi model (for example the Pi 3B+), you may also need to update the kernel and the firmware using the instructions above. Third-party solution Node-RED is installing on the Raspberry Pi. The script will: Remove the pre-packaged version of Node-RED & Node.js. Install the latest version of Node-RED using npm and the latest Node.js LTS (If. As part of the major upgrade process (when you sudo apt install nodejs), the current Node version installed on your system (node .10.29, in your case) will be removed and replaced with the updated version of Node you specified. At that point, you will be good to go and can follow the Minor/Patch Version Upgrades section of my post for minor (security, etc.) updates in the future
