Issues With Selenium: Adding Path To Chrome-Webdriver




hello and good day dear all 



due to some tests with a selenium-based-parser i wanted to install the package on my machine. on a win 10 system see what has happened. --- see below the script... 


from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
import time
#--| Setup
options = Options()
browser = webdriver.Chrome(executable_path=r'C:\cmder\bin\chromedriver.exe', options=options)
#--| Parse or automation
user_name = browser.find_element_by_css_selector('#user_login')
password = browser.find_element_by_css_selector('#user_pass')
submit = browser.find_elements_by_css_selector('#wp-submit')[0]
# Example send page source to BeautifulSoup or selenium for parse
soup = BeautifulSoup(browser.page_source, 'lxml')
use_bs4 = soup.find('title')
#print('*' * 25)
#use_sel = browser.find_elements_by_css_selector('div > div._1vC4OE')

after having had a closer look at the preliminaries i - note: i had to install wheel first i finally got there to test the script- 
see the full story:_ finally i installed wheel - so i got back the following: 

Windows PowerShell

PS C:\WINDOWS\system32> pip install -U selenium
Requirement already up-to-date: selenium in c:\program files\python37\lib\site-packages (3.141.0)

Could not build wheels for selenium, since package 'wheel' is not installed.

now i will testrun the selenium code from above... and i did it: now i get back the following: 

traceback (most recent call last):

i guess that i now have to set the paths of the chromedriver in the code.

You can test if it actually is in the Python PATH, if you open a cmd and type in chromedriver and hit Enter. If Starting ChromeDriver 2.15.322448 is appearing, the PATH is set appropriately and there is something else going wrong. Then try the following:

Download ChromeDriver 

Then you have multiple options:

  • Add it to your system path
  • Put it in the same directory as your python script
  • Specify the location directly via executable_path
driver = webdriver.Chrome(executable_path='C:/path/to/chromedriver.exe')
