Selenium-Webdriver and PhantomJS on Openshift/Ruby - Error: "Unable to find phantomjs executable"

I am working on a web testing project on the Openshift platform (free tier) using Selenium-webdriver, watir, PhantomJS headless browser, etc. and am encountering an error for which I can not find a solution.

Background: I am fairly new to Ruby, Linux, web application testing, etc. I have worked to install an Openshift (free tier) Ruby gear and have been successful on that part. I can SFTP into the gear via Filezilla, can SSH into the App via Putty and have a Windows 10 desktop that has the OpenShift tools on it (GIT, etc.) I have installed Selenium-Webdriver and PhantomJS.

I am trying to work through the below "Web Application Testing in Ruby" guide to implement the below code on the Openshift platform.

Guide: https://leanpub.com/watirbook/read#leanpub-auto-irb-interactive-ruby-shell

Code I am trying to implement:

require "selenium-webdriver"
browser = Selenium::WebDriver.for :phantomjs
browser.get "http://google.com"
p browser.current_url
p browser.title
browser.find_element(name: "q").send_keys "watir"
browser.find_element(name: "q").clear
p browser.find_element(name: "q").attribute(:name)
p browser.find_element(name: "q").attribute(:class)
p browser.find_element(name: "q").attribute(:type)
p browser.find_element(name: "q").
attribute(:autocomplete)
browser.save_screenshot "phantomjs.png"
p browser.page_source
p browser.find_element(name: "q").
attribute(:outerHTML)
browser.quit

When I run this code as instructed via the following command:
ruby headless_phantomjs.rb

I get the following error:

/var/lib/openshift/MYAPPID/.gem/gems/selenium-webdriver-2.47.1/lib/selenium/webdriver/phantomjs/service.rb:39:in `executable_path': Unable to find phantomjs executable. (Selenium::WebDriver::Error::WebDriverError)
    from /var/lib/openshift/55e5f36b89f5cf105a000102/.gem/gems/selenium-webdriver-2.47.1/lib/selenium/webdriver/phantomjs/service.rb:47:in `default_service'

    from /var/lib/openshift/55e5f36b89f5cf105a000102/.gem/gems/selenium-webdriver-2.47.1/lib/selenium/webdriver/common/driver.rb:64:in `new'
    from /var/lib/openshift/55e5f36b89f5cf105a000102/.gem/gems/selenium-webdriver-2.47.1/lib/selenium/webdriver/common/driver.rb:64:in `for'
    from /var/lib/openshift/55e5f36b89f5cf105a000102/.gem/gems/selenium-webdriver-2.47.1/lib/selenium/webdriver.rb:86:in `for'
    from headless_phantomjs.rb:7:in `<main>'

In IRB in Ruby I can use the Path command to find the Path: /opt/rh/ruby193/root/usr/bin/ but can't get to it or edit it.

I have verified that the phantomJS executable is in the following directory under my app: /app-root/data/phantomjs/bin

Question: How do I get past this error and let Selenium webdriver see path for PhantomJS?

Help appreciated....

This issue is caused by failing to find phantomjs. So you need to install it first and add the path.

For example in Windows, test.rb

require 'selenium-webdriver'
require 'phantomjs'

Selenium::WebDriver::PhantomJS.path = 'C:\\Users\\name\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe'
driver = Selenium::WebDriver.for :phantomjs
driver.navigate.to "http://google.com"
puts driver.title  
driver.quit

When the PhantomJS executable is not in your path, you will need to use the path= method tell Selenium-WebDriver where to look:

require "selenium-webdriver"

Selenium::WebDriver::PhantomJS.path = '/app-root/data/phantomjs/bin/phantomjs.exe'

browser = Selenium::WebDriver.for :phantomjs
