Can't open phantom.js - double single quotes in path

[theguythatrepeatedit]

Hi there, I am losing my mind. My setup is vanilla wraith on Windows - I have tried running with all versions of Ruby. Every time I launch it outputs Can't open ''XXX:/Ruby22/lib/ruby/gems/2.2.0/gems/wraith-3.2.0/lib/wraith/javascript/phantom.js'' (note the double single quotes)

The file is definitively there! I even tried hardcoding it form inside wraith without success

How can I get out of this situation ?

Hi @theguythatrepeatedit it looks like when you passed -verbose as a command line parameter, it didn't actually run it in verbose mode (verbose mode should tell me what version of Ruby, Phantom, Wraith you have, etc).

Can you try adding verbose: true to your yml file and then paste the output of your command here?

Thanks

Good day!

Does XXX:/Ruby22/lib/ruby/gems/2.2.0/gems/wraith-3.2.0/lib/wraith/javascript/phantom.js definitely exist?

If you run more XXX:/Ruby22/lib/ruby/gems/2.2.0/gems/wraith-3.2.0/lib/wraith/javascript/phantom.js you should see output like this: https://github.com/BBC-News/wraith/blob/master/lib/wraith/javascript/phantom.js

If more doesn't give you the file contents, it probably can't find the file. Let's just check that first.

[theguythatrepeatedit]

Interesting!

more C:/Ruby22/lib/ruby/gems/2.2.0/gems/wraith-3.2.0/lib/wraith/javascript/phantom.js
Invalid parameter - /Ruby22

Then I flip the slashes around:
more C:\Ruby22\lib\ruby\gems\2.2.0\gems\wraith-3.2.0\lib\wraith\javascript\phantom.js
// modules
var system = require('system'),
page = require('webpage').create(),
helper = require('./_helper.js')(system.args[2]);
.......
.................

I hardcoded it now in wraith.rb and ran into the exact same problem on the next opportunity 😃

Thanks alot Chris ! I probably should have spotted that myself hehe, will probably get around the other ones my self ;)

Have a good weekend

Hi,

I am now getting this issue having upgraded PhantomJs to 2.0 from 1.9.

I have been successfully running Wraith with 1.9 for a while. If I switch back to 1.9 everything starts working again.

I am on windows.

Any ideas?

[ChrisBAshton]

Could you raise a new issue please, @SimonKeep ?

There are some instructions in the 'New Issue' screen for giving us some useful debug information.

Thanks

I am getting the same error

The file really exists :

I get the same error as @theguythatrepeatedit when I do the command
more C:/Ruby23-x64/lib/ruby/gems/2.3.0/gems/wraith-3.2.0/lib/wraith/javascript

I get this error :
Invalid parameter - /Ruby22

Because of this error I cannot get wraith to work

Windows 10

[SimonKeep]

Which version of PhantomJS are you using? You may need to use 1.9 with windows. See #444.

[stevenbriscoeca]

@SimonKeep It is working now thank you

If this helps anyone :
npm install -g phantomjs@1.9.19 and it works on windows

This should be documented because anyone that is on windows won't be able to use wraith
