Unable to run tests using protractor on SauceLabs

Unable to run tests using protractor on SauceLabs launched from Travis CI

Step to reproduce.

1. I have configured .travis.yml (https://docs.travis-ci.com/user/sauce-connect/) to use Sauce Connect to allow Travis runs scripts on Sauce Labs. Travis log displayed that connection was successful:
   27 Nov 06:48:18 - Starting Selenium listener...
   27 Nov 06:48:18 - Establishing secure TLS connection to tunnel...
   27 Nov 06:48:18 - Selenium listener started on port 4445.
   27 Nov 06:48:19 - Sauce Connect is up, you may start your tests.
2. Start e2e test with protractor.config.js configuration.
3. Expected result: All e2e tests are passed/failed.
   Actual result: Tests aren't started. The following error is displayed:

I used protractor@3.0.0.

For more details please refer to the protractor configuration file and full travis log (https://s3.amazonaws.com/archive.travis-ci.org/jobs/93474859/log.txt)

This error is due to the fact that Protractor 3.x.x does not work with node versions < 4. It looks like you are using node v0.12.4 which is not compatible.

You will need to downgrade to protractor 2.x.x or upgrade your version of node to 4 or greater. You can see the exception is generated from the new es6 arrow syntax in your stacktrace:

[chrome #2] vlog(2, () => this + ' scheduling notifications', this);
[chrome #2] ^
[chrome #2] SyntaxError: Unexpected token )

In the future please direct debugging or usage questions to Stackoverflow or post in the Gitter Channel to get help.

From the the getting help section of the README:

Please ask usage and debugging questions on StackOverflow (use the "protractor" tag) or in the Angular discussion group. (Please do not ask support questions here on Github.)
