Python selenium webdriver “Session not created” exception when opening Chrome

问题

Here's my code for opening Chrome:

from selenium import webdriver 
driver=webdriver.Chrome('C:\\Users\\Imran\\AppData\\Local\\Programs\\Python\\Python36\\selenium\\chromedriver.exe')

Error when running program:

Traceback (most recent call last):

    driver = webdriver.Chrome('C:\\Users\\Imran\\AppData\\Local\\Programs\\Python\\Python36\\selenium\\chromedriver.exe')

Getting the following exception:

selenium.common.exceptions.WebDriverException: Message: session not created exception

回答1:

Update your chromedriver to 2.24 version from the given url:

http://chromedriver.storage.googleapis.com/index.html?path=2.24/

That worked for me.

回答2:

Setting LANG=en_US.UTF-8 before executing my script works for me. See this: https://bugs.chromium.org/p/chromedriver/issues/detail?id=1552#c43

In Python:

import os
os.environ["LANG"] = "en_US.UTF-8"

回答3:

To install the chromedriver on windows, download and unzip the chromedriver_win32.zip and add the path to the folder containing the chromedriver.exe in the environment variables setting [System properties - Advanced system settings - Environment variables].
