Error when running demo code provided about node-scraper

[abhinavxrai]

Anyone have any ideas?
I rebuilt my instance and re-installed node and scraper. Same issue

I'm having the same issue :(

[abhinavxrai]

It seems this issue started around the same time as 'request' was moved to a different tree. Are there any hard-coded links in scraper?

The issue seems to be with jsdom. An issue has already been raised here https://github.com/tmpvar/jsdom/issues#issue/149

[mape]

Seems jsdom defaults to:

jQueryTag.src = path || 'http://code.jquery.com/jquery-latest.js';

and that doesn't work all as it is now. I therefore reverted to a local 1.3.2 version of jQuery.

It also seems to break on script tags in the supplied source so to prevent that I temporarily do:

body = body.replace(/<(\/?)script/g, '<$1nobreakage');

[mape]

So if it was not working for you before, update (new version on npm) and it should work.

[abhinavxrai]

Interesting, thanks for the suggestion, but even with the latest version (0.08) it fails.

Also, it seems jQueryTag.src = path || 'http://code.jquery.com/jquery-latest.js'; should be valid

[abhinavxrai]

I raised the issue with jsdom

[abhinavxrai]

In your code I noticed:
'/../deps/jquery-1.3.2.js'

so I added a local copy of jquery 1.3.2 and still same error.

I got my own jquery scraping thing working last night by doing something similar to this:

https://github.com/chriso/node.io/blob/master/lib/node.io/dom.js#L49

not sure if that helps...

cheers!

[mape]

jquery-1.3.2.js is already added in the project so you shouldn't have to add it on your own.

I'm not having any issues so a stack trace would be helpful.

And what example do you run to get that result? Or what code.

[abhinavxrai]

I'm using your demo code:

var scraper = require('scraper');
scraper('http://search.twitter.com/search?q=javascript', function(err, jQuery) {
if (err) {throw err}

jQuery('.msg').each(function() {
    console.log(jQuery(this).text().trim()+'\n');
});

});

I just rebuilt my server and installed node and scraper (0.0.8) from scratch

[mape]

Hmm I can not reproduce that error.

[abhinavxrai]

Interesting...
I'm using [email protected]
[email protected]
[email protected]

I'll try to use the "advanced" demo code and see if I can replicate it.

[abhinavxrai]

I'm running
[email protected]
[email protected]

What versions are you running?

[mape]

node v0.4.1
npm 0.3.9

[abhinavxrai]

I downgraded to
[email protected]
still the same error.

TypeError: Cannot read property 'prototype' of undefined

My server is running on rackspace cloud, but I've successfully used scraper before.

[DenisMir]

I got the error as well. Here is my setup:

node v0.4.1
npm 0.3.9

I am using the latest scraper version installed via npm. I would appreciate some help.
