urllib3.exceptions.ProtocolError: ('Connection aborted.', error(10054, 'An existing connection was forcibly closed by the remote host'))

问题

I am trying to open a website on chrome using Python Selenium chromedriver. Chrome browser is opening (with warnings) and the url is not opening.

Version details : Chrome : 68.0.3440.106 selenium : 3.14.0 chromedriver : 2.20 python : 2.7

I am using below code :

import time
from selenium import webdriver
import selenium
driver = webdriver.Chrome(\"C:/Python27/chromedriver.exe\")
driver.get(\"https://vancouver.craigslist.ca/\")
print(driver.title)
time.sleep(8)
driver.quit()

I am getting below error:

Am i missing something? Really appreciate your help

回答1:

This error message...

urllib3.exceptions.ProtocolError: ('Connection aborted.', error(10054, 'An existing connection was forcibly closed by the remote host'))

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

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

You are using chromedriver=2.20
Release Notes of chromedriver=2.20 clearly mentions the following :

Supports Chrome v43-48

You are using chrome=68.0
Release Notes of ChromeDriver v2.41 clearly mentions the following :

Supports Chrome v67-69

So there is a clear mismatch between ChromeDriver v2.33 and the Chrome Browser v65.0

Solution

Upgrade ChromeDriver to current ChromeDriver v2.41 level.
Keep Chrome version between Chrome v67-69 levels. (as per ChromeDriver v2.41 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Execute your @Test.
