phantom stdout: TypeError: undefined is not an object (evaluating 'phantom.args[0]')

[matthewmueller]

Running into this when trying to run the examples:

  nightmare queueing action "evaluate" +0ms
  nightmare run +5ms
  nightmare .setup() creating phantom instance on port 12301 +1ms
phantom stdout: TypeError: undefined is not an object (evaluating 'phantom.args[0]')


phantom stdout:   /Users/matt/Playground/node_modules/nightmare/node_modules/phantom/shim.js:5421
  /Users/matt/Playground/node_modules/nightmare/node_modules/phantom/shim.js:5599
  /Users/matt/Playground/node_modules/nightmare/node_modules/phantom/shim.js:159
  /Users/matt/Playground/node_modules/nightmare/node_modules/phantom/shim.js:11 in require

This could definitely be an issue with phantomjs on 10.10, but any ideas?

[matthewmueller]

Oh, it could also be because I'm running 2.0.0:

$ phantomjs --version
2.0.0 (development)

[matthewmueller]

Yep, that was it. I guess it's a good heads up ;-)

Great project!

[reinpk]

ah, that is a good heads up, thanks!

@reinpk What's the outlook on supporting PhantomJS 2.0.0? Do you have any idea how much effort would be involved, and how much the Phantom devs have actually been changing the interfaces? 1.9.7 does a pretty terrible job of rendering interactive D3.js, and my attempts at bridging the gap in my app between what D3 wants and what 1.9.7 supports haven't worked out so far. So far interactive D3.js looks great in PhantomJS 2.0.0.

[bprodoehl]

Sorry, I see the same error just running phantomjs-node examples, so I don't think this has anything to do with nightmare.

[reinpk]

ah, bummer, not sure i haven't had a chance to investigate 2.0.0 at all yet

[fernandopasik]

I'm having the same issue but with phantom 1.9.7, but I'm not running the examples

phantom stdout: TypeError: 'undefined' is not an object (evaluating 'x.options')

[mariodu]

My OS is MacOS 10.10,and phantomjs is 2.0.0 (development),has this problem,please fix it

[bprodoehl]

@mariodu The problem lies in a package that nightmare depends on. I have created a ticket under that project here: https://github.com/sgentle/phantomjs-node/issues/208

@fernandopasik are you sure the problem isn't in your code? I'm not finding "x.options" anywhere in nightmare or phantomjs-node.

[dtothefp]

I've forked Node PhantomJS and hacked around with it to install the only "stable" version for Mac of Phantom 2.0.0 I could find:

Version I'm using: https://github.com/eugene1g/phantomjs/releases/download/2.0.0-bin/phantomjs-2.0.0-macosx.zip
Fork: https://github.com/dtothefp/phantomjs

So, you could just require the binary path

var phantomPath = require('phantomjs').path
var nightmareOptions = {
  path: phantomPath.substring(0, phantomPath.lastIndexOf('/') + 1),
}

@bprodoehl it looks like you have shimmed the phantomjs-node package and the binary works fine with it. I just tried using the binary with Nightmare and it seems to work fine.

Also, I saw in your PR that the previous phantom.args are defined on system.args. Is this the syntax moving forward with PhantomJS 2.0.0?
