Node.js is an open-source, cross-platform, JavaScript run-time environment that executes JavaScript code outside of a browser.

Install or Update NVM

Install/Update Use Script

1
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash

The script clones the nvm repository to ~/.nvm and adds the source line to your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).

Note: If the environment variable $XDG_CONFIG_HOME is present, it will place the nvm files there.

export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" --no-use  # using nvm until manually run `nvm use default`.

After running the install script, close current terminal and open a new terminal,
