selenium遠程webdriver錯誤

Question

我試着設置了selenium的遠程webdriver。在我的遠程機器上，selenium服務器正在運行，並接收到我從本地打出的請求。但在我的地方，爲什麼會出現這些錯誤？不知道

from selenium import webdriver 
from selenium.webdriver.remote.webdriver import WebDriver as RemoteWebDriver 
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities 
from selenium.webdriver import ChromeOptions 
import os 

chromedriver = '/Users/guru/Downloads/chromedriver' 
os.environ["webdriver.chrome.driver"] = chromedriver 
driver = RemoteWebDriver(
    command_executor='http://ec2-XXX-XXX-XXX-XXX.compute.com:4444/wd/hub', 
    desired_capabilities=DesiredCapabilities.CHROME) 

driver.get('http://voot.com') 

爲什麼會出現這個錯誤

設置遠程機器上要運行的測試下面的東西。

設置使用以下命令chromedriver父文件夾的路徑系統PATH：

export PATH = /Users/prashant/Downloads/:$PATH 
echo $PATH 

你應該設置輕拍至.exe文件如下：

chromedriver = '/Users/guru/Downloads/chromedriver/chromedriver.exe' 
os.environ["webdriver.chrome.driver"] = chromedriver
