var html = fs.readFileSync(file, 'UTF-8');

$(html).find('p').each(function(index) {
    var content = $(this).html();

    console.log('Paragraph ' + (index + 1) + ': ' + content);
});

I had code that worked fine a month ago, but started to display this error when I upgraded to the latest jquery via npm. If I only knew how to get back that older version, then the problem would go away.

This seems to have fixed it:

npm install jquery
npm install jsdom



// Define window
var jsdom = require("jsdom");
var window = jsdom.jsdom().createWindow();
var $ = require("jquery")( window );

jQuery requires a full DOM implementation, which you don't have on the server.

To parse HTML text, you should use a simpler library called Cheerio, which has a jQuery-like API but does not use a DOM.

Alternatively, you could use JSDOM to fake a browser DOM on the server (this is slower).
