    1. Verify if the node is completely uninstalled or not using node -v command.

    If the output shows command not found then you are successfully uninstalled.

    node verify uninstallation

    Installing node and npm using nvm

    We are using the node version manager (nvm) to download and install the latest version of node.js (with npm included).

    1. Run the following command in your terminal to install the nvm.
    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
    1. If your using bash or zsh, you need to add the following code to ~/.bashrc or ~/.zshrc files.

    To open bashrc file in vscode use code ~/.bashrc command.

    To open zshrc file in vscode use code ~/.zshrc command.

    export NVM_DIR="$HOME/.nvm"
    [ -s "$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
    1. Verify the nvm installation by running the below command.
    nvm --version
    
    # 0.35.3

    If the output shows a version number then you are successfully installed.

    1. Now, run the following command to download and install the latest version of node.
    nvm install node

    If you want to install a long term support (LTS) version use this command.

    nvm install --lts

    or a specific version.

    nvm install 12.1.4
    1. To use the node, we need to set the default node version by using this command.
    nvm alias default node
    1. Verify the node and npm installation.
    node -v
    npm -v

    Output:

    v13.13.0
