黃瓜無頭xvfb ubuntu

Question

我試圖在亞馬遜EC2上設置一個Jenkins構建服務器。我正計劃在無頭模式下運行我的黃瓜測試套件。 我是能夠成功地在IRB

require 'watir-webdriver' 
require 'headless' 
headless = Headless.new 
headless.start 
b = Watir::Browser.new(:chrome) 
b.goto("www.google.com") 
b.title 
b.close 
headless.destroy 

運行無頭，但如果我添加下面我env.rb

if ENV['HEADLESS'] 
    require 'headless' 
    headless = Headless.new 
    headless.start 
    at_exit do 
    headless.destroy 
    end 
end 

和運行

cucumber ENV=HEADLESS features/test.feature:25 

我碰到下面的錯誤。

任何幫助將不勝感激。謝謝！！

的問題是在命令行參數的env

cucumber HEADLESS=true features/test.feature:25 

，而不是

cucumber ENV=HEADLESS features/test.feature:25
