How to install Node.js 8/9 in Ubuntu/Xubuntu

• Simply go to the official website of Node.js or click here to download th latest version of node.js.
• After you downloaded the package, extract it using the command :
  tar -xf name_of_package
• Rename the folder just made after extraction of the package to nodejs. Command is this :mv name_of_package nodejs

• Copy the folder ‘nodejs‘ inside the ‘bin‘ folder in root directory using the command:
  sudo cp -r nodejs /bin
• At this point, you need to add the nodejs binaries in the PATH variable so that they can be executed from anywhere.
  There are two ways to do this. I am using the less popular way to keep things easy. What you have to do is that copy the files inside nodejs/bin
  Use this command : sudo cp /bin/nodejs/bin/*/usr/local/bin/
• Okay all done. Check the version of Node.js and NPM using the following commands :
  • node -v
  • npm -v
• If you face any error while checking the version of npm, one like this “Error: Cannot find module ‘../lib/utils/unsupported.js’ “ do the following :
  • Remember the ‘nodejs’ folder in the ‘Downloads’?
  • Go to Downloads folder, and give the following series of commands :
    • Delete the ‘npm’ in usr/local/bin
      Use this command: sudo rm usr/local/bin/npm
    • cd ~/Downloads [Go to the Downloads Folder]
    • cd nodejs/bin [Go inside the binaries folder of node.js]
    • Execute npm from inside the node binaries file to install latest version of NPM globally use the following command:
      sudo ./npm install npm@latest -g
    • Done !
• Now finally you can use the latest NPM v5.0.1 and Node.js v8/9
• Suggestions/corrections are welcome
• Thanks ! Happy coding
