问题描述

当我使用Python使用Selenium执行此代码时:

When I'm executing this code with Selenium using Python:

from selenium import webdriver
from selenium.webdriver.common.by import By
import time
driver = webdriver.Chrome(executable_path=r'/Users/qa/Documents/Python/chromedriver')

发生错误:

   Traceback (most recent call last):

推荐答案

此错误消息...

selenium.common.exceptions.SessionNotCreatedException: Message: session not created
from disconnected: unable to connect to renderer

...表示 ChromeDriver 无法启动/产生新的 WebBrowser ，即 Chrome浏览器会话.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

您需要考虑一个事实:

• 在使用 Mac OS X 时，必须使用 Value 来支持 Key executable_path:

• As you are using Mac OS X the Key executable_path must be supported with a Value as :

'/Users/qa/Documents/Python/chromedriver'

因此行将是:

So line will be:

driver = webdriver.Chrome(executable_path='/Users/qa/Documents/Python/chromedriver')

注意:路径本身是原始路径，因此您无需添加开关r并放下它.

Note: The path itself is a raw path so you don't need to add the switch r and drop it.

此外，确保系统上的/etc/hosts包含以下条目:

Additionally, ensure that /etc/hosts on your system contains the following entry :

127.0.0.1 localhost.localdomain localhost
#or
127.0.0.1 localhost loopback
