python - DeprecationWarning: use options instead of chrome_options error using ChromeDriver and Chrome through Selenium on Windows 10 system

Question

Trying to run this code on my windows 10 machine https://github.com/KalleHallden/reddit_automations/blame/master/movie-tickets.py

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from decouple import config
import time

# the way to locate the button or thing you want on a website in chrome is
# by pressing cmd + shift + c and then you can use your mouse to find the 
# info on the element that you want and you can copy the full xpath.

options = webdriver.ChromeOptions()
# options.add_argument('--ignore-certificate-errors')
# options.add_argument('--incognito')
# options.add_argument('--headless')
driver = webdriver.Chrome("/Users/kalle/Downloads/chromedriver83", chrome_options=options)
driver.get(config('THEATRE_SITE'))
# for some odd reason you need to reload the site for it to load.
# possibly a bug of the theatre site
driver.get(config('THEATRE_SITE'))
time.sleep(3)
# select city
button = driver.find_element_by_xpath('/html/body/div[1]/div[3]/div/div/div[1]/div/div[2]/ul/li[1]/label/input')
button.click()

# save city
button = driver.find_element_by_xpath('/html/body/div[1]/div[3]/div/div/div[2]/span/button')
button.click()
time.sleep(2)

# proceed to tickets tab
button = driver.find_element_by_xpath('/html/body/div[1]/nav/div[2]/div[2]/div[1]/ul[1]/li[1]/a')
button.click()
time.sleep(2)

# select the movie you want (should be more specific than just selecting the first one but whateva)
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[2]/div/div/div/div[2]/div/div[2]/div[2]/div[2]/ul/li[1]/ul/li/div/div[1]/div/span[2]/a')
button.click()
time.sleep(1)

# select the time you want to go
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[1]/div/div/div/div[4]/section/div/div[2]/div[2]/ul/li/ul/li[1]/div/span/span[3]/span[2]/span')
button.click()
time.sleep(1)

# choose amount of people
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[2]/div/div/div/div/section/div/div[2]/div/button')
button.click()
time.sleep(2)

# choose seats
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[1]/div/div/div/div[2]/section/div[3]/div[2]/button')
button.click()
time.sleep(2)

# pay
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[1]/div/div/div/div[2]/section/div[4]/div/div[2]/button/span')
button.click()

I have all the correct programs installed:

• running python 3.8
• have chrome webdriver installed
• running version 84 stable chrome web browser

When I run the program it opens chrome however I get a blank web page with nothing on there but some text which says "data:." that is all nothing else.

This is the error I get in VS code:

:Usersuser>python c:/chromedriver_win32/movie-tickets1.py
c:/chromedriver_win32/movie-tickets1.py:15: DeprecationWarning: use options instead of chrome_options
  driver = webdriver.Chrome(executable_path=r'C:chromedriver_win32chromedriver.exe', chrome_options=options)

    raise UndefinedValueError('{} not found. Declare it as envvar or define a default value.'.format(option))
decouple.UndefinedValueError: https://www.google.co.uk not found. Declare it as envvar or define a default value.

Any help would be much appreciated, I am unsure why decouple is not working.

Answer 1

This error message...

DeprecationWarning: use options instead of chrome_options

...implies that in your program you have used chrome_options to initiate a Selenium driven ChromeDriver initiated google-chrome Browsing Context.

chrome_options is deprecated now and you have to use options instead as well as pass the absolute path of the ChromeDriver along with the extension.

Solution

As you are triggering your tests on a windows-10 system, effectively you line of code will be:

options = webdriver.ChromeOptions()
options.add_argument('--headless')
driver = webdriver.Chrome(executable_path=r'C:chromedriver_win32chromedriver.exe', options=options)
