ModuleNotFoundError: No module named 'webdriver_manager' error using Webdriver Manager for Selenium Python

Question

I am creating a project to automatically open a page, and I installed Selenium, but it says that there:

no such module as webdriver_manager

And the directory "C:\Users\Nina\chromedriver.exe" is not valid.

Here's my code:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
import webdriver_manager as manager
from selenium.webdriver.common.by import By

s=Service(manager.ChromeDriverManager().install())
driver = webdriver.Chrome(service=s)
driver.maximize_window()
driver.get('https://cms.instructure.com/courses/500236/pages/week-14-november-22-23')

How can this error be fixed?

Can you update the question with the error stack trace?

This error message...

ModuleNotFoundError: No module named 'webdriver_manager'

...implies that the webdriver_manager wasn't properly installed.

Reasons

Possibly you installed webdrivermanager as:

pip install webdrivermanager

Or you have installed webdriver-manager as:

pip install webdriver-manager

Hence you see the error.

Solution

Instead of those, you need to install webdriver_manager as:

pip3 install webdriver_manager

Update your code as:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

s=Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s)
driver.maximize_window()
driver.get('https://cms.instructure.com/courses/500236/pages/week-14-november-22-23')
