run all these steps as root to install nvm and node globally for all users. if you want to install node on a per-user basis, this guide is not for you, you need to modify the steps. 

remove any nodejs versions installed via the packet manager of your os .. for example linux: 
  apt remove --purge nodejs

install the latest version of nvm. note, this will install nvm globally for all users. 
<code>
export XDG_CONFIG_HOME="/opt"
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/$(curl -s https://api.github.com/repos/nvm-sh/nvm/releases/latest | grep "tag_name" | cut -d : -f 2,3 | tr -d ' ",')/install.sh | bash
echo 'export NVM_DIR="'$XDG_CONFIG_HOME'/nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion' > /etc/profile.d/nvm.sh
