    # docker image.
    # ---------------------------------------------------------
    # Currently, it is designed for installing:
    # nvm, npm, nodejs, and yarn
    # The version can be specified by users.
    # ---------------------------------------------------------
    # For those users who want to install all latest tools,
    # please run:
    # ```bash
    # ./install-nodejs.sh --all
    # ```
    # ------------------------
    # NodeJS is installed by NVM and NPM. For those users who
    # do not want to install yarn, please run:
    # ```bash
    # ./install-nodejs.sh --basic --nodejs
    # ```
    # ------------------------
    # For installing a specific version, please run:
    # ```bash
    # ./install-nodejs.sh --all nvm=0.40.1 nodejs=20.17.0 yarn=4.4.1
    # ```
    # Note that the version will take effect only when the tool
    # will be installed. For example, if --yarn or --all is not
    # specified, yarn=? will not take effects.
    # ------------------------
    # For those users using root mode, please add the option
    # --sudofix like this::
    # ```bash
    # ./install-nodejs.sh ... --sudofix
    # ```

    # Make bashline configurations.
