Error: spawn EPERM and Error: spawn ENOENT

I'm trying to convert a markdown to pdf using the npm package markdown-pdf with the code below of index.js and I'm getting these errors after run node index.js.

The first error I got is on my Windows 10 Host Machine, and the second one is on my Ubuntu Guest VirtualBox VM.

Any idea of how to solve this? Anything related with phantomjs package?

index.js

var markdownpdf = require("markdown-pdf"),
             fs = require("fs")

markdownpdf().from("./README.md").to("./curriculo.pdf", function() {
    console.log("Converted to PDF successfully!")
})

Terminal Output Error - Windows Host VM

    throw errnoException(err, 'spawn');
