                                                                                Following the path of ruby, developers of node also created node version manager (nvm) just like ruby version manager (rvm) to manage multiple node versions in the same operating system. So guys in this post i am gonna show you all how to install node version manager in ubuntu 16.04 operating system.

so basically open the terminal and run this command

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash

after running this command run these two command in the terminal

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

and after that load the shell i.e if you're using bash then run this command in terminal

source ~/.bashrc

and if you're using zsh instead of bash then run this command in terminal

source ~/.zshrc

and thats it now you have access to the nvm command line utility.

to install latest version of node and npm into the system just run this command

Thats it. if you wanna learn more than use this command

nvm --help

There are various command available in nvm to manager and pull new node and npm versions.
