Error Message: 'chromedriver' executable needs to be PATH

问题

I just started on Selenium and was able to load up google but now when I run the following code it produces the error:

selenium.common.exceptions.WebDriverException: Message 'chromedriver' executable needs
to be PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Why is it saying "C:Users/Colin/Python/chromedriver" is not a path?

from selenium import webdriver

browser = webdriver.Chrome("C:Users/Colin/Python/chromedriver")
browser.get('http://www.google.com')

browser.quit()

回答1:

While working with Selenium v3.x, ChromeDriver and Chrome Browser you may need to pass the argument executable_path along with the absolute path of the ChromeDriver binary through either of the following options:

• Double back slashes i.e. (\\)
• Single back slash i.e (\) along with the raw (r) switch.
• Binary extension i.e. (.exe)

So you have to change the line :

browser = webdriver.Chrome("C:Users/Colin/Python/chromedriver")

With :

browser = webdriver.Chrome(executable_path=r'C:\Users\Colin\Python\chromedriver.exe')
