Node Version Manager (NVM)

Why NVM ?

  • Suppose you are core developer of Node Js who reviews code of many node js developers
  • All the different applications code that you review might note be running on the same exact version of Node JS.
  • So now you cannot re-install the Node Js everytime you encounter a new version so, NVM helps you to change the Node version as you please.


  • There are many tools available on internet to manage node versions
  • We are going to use NVM in our case
  • Below is the link for documentation
  • Run below command to install nvm
----download using below command
curl -o- | bash
----reload the bashrc
source ~/.bashrc
----List of node version

----Install a node version

----List of installed node version installed on your system

----Change the node version using nvm
nvm use v14.15.1
----Check node version
node -v
----Change Back to system version of nodejs
