Python selenium WebDriverException：打开ChromeDriver时无法访问chrome

Question

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:\Users\alice\Desktop\chromedriver')
driver.get('https://reports.blm.gov/report/LR2000/23/Pub-MC-Geo-Index')

I put it in to a function goTo()

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

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)

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

Answer 1

The error says it all :

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)

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

• You are using chromedriver=2.35
• Release Notes of chromedriver=2.35 clearly mentions the following :

Supports Chrome v62-64

• You are using chrome=65.0
• Release Notes of ChromeDriver v2.36 clearly mentions the following :

Supports Chrome v64-66

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

Solution

• 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.
