Getting errors in the MarkoJs "Getting Started" tutorial

I'm a newbie at Node.js and Marko. Getting errors in the "Installing" section.

Getting the error when I try the following command:

lasso --main client.js --plugins lasso-marko --inject-into index.html

Any help will be great.
Error:

PS C:\Data\Repository\personal-finance\web-site\hello-world> lasso --main client.js --plugins lasso-marko --inject-into index.html

        "lasso-marko"
    ]
}

The command you are running references client.js (In the current working directory) as the js entry point. Does this file exist on your machine?
