PhantomJS driver wont start

Question

I'm having issues starting up the PhantomJS driver. It works just fine on my local machine (OSX) but I'm having issues getting it started on the server (Linux).

Here's the code that causes the issue:

DesiredCapabilities dcap = new DesiredCapabilities();
String[] phantomArgs = new  String[] { "--webdriver-loglevel=NONE" };
dcap.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, phantomArgs);
dcap.setCapability("phantomjs.binary.path", "/usr/local/bin/phantomjs");
WebDriver driver = new PhantomJSDriver(dcap);

And here's the stack trace of the issue:

I built the PhantomJS from source and had it working before - it ran through the tests just fine. Additionally, it works locally on my machine. Any thoughts on what could be causing the issue?

Answer 1

The problem was due to the phantomjs's inability to write to the log file. Changing the file permissions of the log file resolved the issue.
