Error: spawn EPERM and Error: spawn ENOENT

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

The first error below 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?

#### index.js
```js
var markdownpdf = require("markdown-pdf"),
fs = require("fs")

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