I cannot get nightmare.js to work on a Ubuntu Linux 14.04 server [via DigitalOcean].
I installed PhantomJS (1.9.8) and Node (4.2.4), and they work well, as far as I can tell.
For example, when I run this:
phantomjs loadspeed.js http://www.yahoo.com
with loadpeed.js containing this:
"use strict";
var page = require('webpage').create(),
system = require('system'),
t, address;
if (system.args.length === 1) {
console.log('Usage: loadspeed.js <some URL>');
phantom.exit(1);
} else {
t = Date.now();
address = system.args[1];
page.open(address, function (status) {
if (status !== 'success') {
console.log('FAIL to load the address');
} else {
t = Date.now() - t;
console.log('Page title is ' + page.evaluate(function () {
return document.title;
}));
console.log('Loading time ' + t + ' msec');
}
phantom.exit();
});
}
I get the following output:
Page title is Yahoo
Loading time 700 msec
However, when I try to run a simple nightmare:
node --harmony hello_nightmare.js
with hello_nightmare.js containing this:
var Nightmare = require('nightmare');
var google = new Nightmare()
.goto('http://google.com')
.wait()
.run(function(err, nightmare) {
if (err) return console.log(err);
console.log('Done!');
});
I get no output; it seems to me that I just hit 'Enter' on the command line.
I also tried an example on the github nightmare site:
npm install nightmare vo
node --harmony hello_nightmare_main.js
with hello_nightmare_main.js containing this:
var Nightmare = require('nightmare');
var vo = require('vo');
vo(function* () {
var nightmare = Nightmare({ show: true });
var link = yield nightmare
.goto('http://yahoo.com')
.type('input[title="Search"]', 'github nightmare')
.click('.searchsubmit')
.wait('.ac-21th')
.evaluate(function () {
return document.getElementsByClassName('ac-21th')[0].href;
});
yield nightmare.end();
return link;
})(function (err, result) {
if (err) return console.log(err);
console.log(result);
});
And it still doesn't work.
How to fix this nightmare?
