    iojs was installed without npm. To install npm either:
      brew install node
    or follow:
      https://github.com/npm/npm#fancy-install-unix

    To prepend iojs to your PATH add to your ~/.bashrc:
      export PATH="#{Formula["iojs"].opt_bin}:$PATH"

    This will also e.g. make npm use iojs's node.
