Python中的Selenium PhantomJS未在ec2實例上運行

這是我的python腳本的代碼片段。我使用PhantomJS 1.9.1和Python 2.7。Python中的Selenium PhantomJS未在ec2實例上運行

def setUp(self): 
    self.driver = webdriver.PhantomJS() 
    self.driver.implicitly_wait(30) 
    self.base_url = "http://***" 
    self.verificationErrors = [] 
    self.accept_next_alert = True 

def test_one(self): 
    driver = self.driver 
    driver.get(self.base_url + "/"+datestring) 
    driver.execute_script('document.querySelector("span.zoom_link").click();') 
    targeturl = anchor_tag.get_attribute("src") 
    datestring =datestring.replace('/','_') 
    urllib.urlretrieve(targeturl, datestring+".jpg")

代碼運行按預期在我的MAC OS本地，但是當我部署在EC2上百分之OS實例相同的腳本，它拋出以下錯誤

Traceback (most recent call last):

您是否在本地和遠程機器上使用相同版本的'Selenium'和'PhantomJS'？ – dm295

它是我的錯誤，PhantomJS版本在我的ec2中是1.9.1，當我將它改爲2.1.1時，它的工作。謝謝 – nithin

使用屬性選擇嘗試，即改變querySelector從

driver.execute_script('document.querySelector("span.zoom_link").click();')

到

driver.execute_script('document.querySelector(\'span[class="zoom_link"]\').click();')
