selenium.common.exceptions.WebDriverException:消息:chrome与ChromeDriver一起使用find_element_by_id Selenium时无法访问错误 [英] selenium.common.exceptions.WebDriverException: Message: chrome not reachable error while using find_element_by_id Selenium with ChromeDriver

问题描述

这是html代码:

< input class="form-control input-lg input auto-complete" id="ymMsgInput" type="text" placeholder="Type your message ..." autocomplete="off" >

代码:

i = s.find_element_by_id("ymMsgInput");

Python-Selenium Chrome Webdriver错误:

Python - Selenium Chrome webdriver error:

Traceback (most recent call last):
  File "<pyshell#19>", line 1, in <module>

推荐答案

错误说明了一切:

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: chrome not reachable

在用户使用的二进制文件之间存在版本兼容性的情况下，会观察到此错误，但绝对不是您所遇到的情况:

This error is observed in case of version compatibility between the binaries which an user uses but definitely this is not your case as you are :

• 使用 chromedriver = 2.36
• 使用 chrome = 65.0

• 硒版本未知

• Using chromedriver=2.36
• Using chrome=65.0

• Selenium version unknown

chromedriver = 2.36 的发行说明明确提到:

Release Notes of chromedriver=2.36 clearly mentions :

Supports Chrome v65-66

但是，自最新版 Chromedriver 2.36 发布以来

But, since the release of the latest Chromedriver 2.36 Selenium users had been facing issues with it. Here is one of the threads :

• 我们发布了最新的Chromedriver 2.36

根本原因与有关的提交有关:

The root cause is related to the commit regarding :

• 删除--disable-infobars

因此，可能有两种解决方案:

So, a couple of possible solution will be to :

使用 ChromeOptions 类来最大化浏览器.

To use ChromeOptions Class to maximize the browser.

一个示例:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("start-maximized")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)

如果问题仍然存在，请考虑以下问题:
