Python selenium WebDriverException:打开 ChromeDriver 时无法访问 chrome [英] Python selenium WebDriverException: chrome not reachable while opening ChromeDriver

问题描述

我正在使用 Selenium Chrome Webdriver 在 Python 3 中打开网页.我想要一个可以打开网页的功能.我原来有:

I am using Selenium Chrome Webdriver to open a webpage in Python 3. I would like to have a function that can open the webpage. I originally had:

driver = webdriver.Chrome(executable_path=r'C:UsersaliceDesktopchromedriver')
driver.get('https://reports.blm.gov/report/LR2000/23/Pub-MC-Geo-Index')

我把它放入一个函数 goTo()

I put it in to a function goTo()

def goTo():
    driver = webdriver.Chrome(executable_path=r'C:UsersaliceDesktopchromedriver')
    driver.get('https://reports.blm.gov/report/LR2000/23/Pub-MC-Geo-Index')

但是，除了 goTo 函数之外，我无法在该页面上执行任何其他操作.尝试时出现错误:

However, I was unable to do any other action on that page outside of that goTo function. When try I get error:

WebDriverException: chrome not reachable
  (Session info: chrome=65.0.3325.181)
  (Driver info: chromedriver=2.35.528161 (5b82f2d2aae0ca24b877009200ced9065a772e73),platform=Windows NT 10.0.16299 x86_64)

有谁知道如何使用函数正确打开页面?

Does anyone knows how can I open the a page properly using a function?

推荐答案

错误说明了一切:

WebDriverException: chrome not reachable
  (Session info: chrome=65.0.3325.181)
  (Driver info: chromedriver=2.35.528161 (5b82f2d2aae0ca24b877009200ced9065a772e73),platform=Windows NT 10.0.16299 x86_64)

您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示:

Your main issue is the version compatibility between the binaries you are using as follows :

• 您正在使用 chromedriver=2.35
• 清楚发布chromedriver=2.35的发布说明提到以下内容:

支持 Chrome v62-64

• 您正在使用 chrome=65.0
• ChromeDriver v2.36 的发行说明明确提到以下内容:

支持 Chrome v64-66

因此 ChromeDriver 版本 (v2.35) 和 Chrome 浏览器 版本 (v65.0)

So there is a clear mismatch between the ChromeDriver version (v2.35) and the Chrome Browser version (v65.0)

• 将 Selenium 升级到当前级别版本 3.11.0.
• 将 ChromeDriver 升级到当前的 ChromeDriver v2.37 级别.
• 将 Chrome 版本保持在 Chrome v65.x 级别.(根据 ChromeDriver v2.37 版本说明)
• 清理您的项目工作区，通过您的 IDE 并重建您的项目，仅使用所需的依赖项.
• 使用 CCleaner 工具清除之前和之后的所有操作系统杂事执行测试套件.
• 如果您的基本Web Client 版本太旧，请通过Revo Uninstaller 并安装 Web Client 的最新 GA 和发布版本.
• 进行系统重启.
• 执行您的@Test.
• 总是在 tearDown(){} 方法中调用 driver.quit() 来关闭 &优雅地销毁 WebDriver 和 Web Client 实例.
• Upgrade Selenium to current levels Version 3.11.0.
• Upgrade ChromeDriver to current ChromeDriver v2.37 level.
• Keep Chrome version at Chrome v65.x levels. (as per ChromeDriver v2.37 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
