Getting " wrong argument type Fixnum (expected String) (TypeError)" while running the Cucumber tests whenever it encounters the Capybara function

I am trying to use capybara in my feature tests, but I keep getting the above error. However, my tests work when non Capybara functions are involved.

Here is the settings in my env.rb:

    Capybara.server_host = 45454
    #Capybara.server_host = host
    Capybara.app_host = 'http://localhost:45454'
    Capybara.default_driver = :poltergeist

PATH variable is also set for Phantomjs

Following is the steps definition file where I am facing the issue.

   Given(/^I navigate to home page$/) do 
     visit '/'
   end

  And /^I take screenshot$/ do
    page.save_screenshot
  end

Following is the feature file

 Scenario: To validate the page shows up
   Given I navigate to home page
     And I take screenshot

Here is the output:

Capybara.server_host needs to be the hostname/ip of an interface Capybara can bind the AUT to, not a number.

You're probably trying to set the port, which would be

Capybara.server_port = 45454

and then judging by your setting of app_host (which probably isn't necessary) you also want to be setting

Capybara.server_host = 'localhost'
