硒远程webdriver错误

Question

我尝试设置 selenium 的远程 webdriver。在我的远程机器上，硒服务器正在运行并接收我从本地发出的请求。但是在我的本地，为什么会出现这些错误？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')

为什么会出现这个错误

在要运行测试的远程机器上设置以下内容。

使用以下命令将 chromedriver 父文件夹路径设置为 System PATH：

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

您应该将 pat 设置为 .exe 文件，如下所示：

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