Issue running "npm run protractor" on Ubuntu 12.04

[declan]

I cloned the repository and followed instructions in the README. Unit tests run with no problem, and the application works in-browser. However, the protractor tests fail with this error message:

------------------------------------
PID: 20518 (capability: chrome #1)
------------------------------------

Starting selenium standalone server...

events.js:72
         throw er; // Unhandled 'error' event
          ^
Error: spawn ENOENT
    at errnoException (child_process.js:998:11)
    at Process.ChildProcess._handle.onexit (child_process.js:789:34)
 [launcher] Runner Process Exited With Error Code: 8

The error is the same as reported in #189. I tried updating JDK, which fixed the issue in that post, but it didn't do anything for me (is JDK even involved on Linux?).

Also, I've already tried running protractor directly

node_modules/.bin/protractor test/protractor-conf.js

and get the same error.

Yes, JDK is involved in Linux. Selenium is a Java application. I had the error above, which disappeared once I installed the latest JDK:

sudo apt-get install default-jdk

This is on 14.04 Trusty Tahr, YMMV. It is also not very obvious that you must be running the server in the background while protractor is running. I assumed it would start the server itself.

I assume this has been solved (if not please open a new issue).

You will indeed need JDK installed, since it is needed for the Selenium Standalone Server used by Protractor (see here for more info).
_{I think you could also work around this, by setting directConnect: true and chromeOnly: true in your protractor.conf.js, but then you won't be able to run tests on other browsers.}
