selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH with GeckoDriver Selenium Firefox

Question

I don't know Pycharm - or Python well enough to troubleshoot just what went wrong. It seems top me as if this simply bit of code should execute but I get a jumble of text that says nothing to me.

Anyone else using Selenium get this error and know how to fix it? The physical code -

"C:\Users\Noah Linton\PycharmProjects\EdgenuityBot\venv\Scripts\python.exe" 
"C:/Users/Noah Linton/PycharmProjects/EdgenuityBot/Edgenuity Bot"
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Process finished with exit code 1

The executive code

 from selenium import webdriver

driver = webdriver.Firefox()
driver.get("https://auth.edgenuity.com/Login/Login/Student")
button = driver.find_element_by_id('LoginSubmit')
button.click()

Answer 1

The error says it all :

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH. 

Which implies that GeckoDriver binary is not in the Classpath

While working with Selenium v3.x you have to download the latest GeckoDriver from this url and store it in your system and mention the absolute path while initiating the webdriver and Web Browser session as follows :

from selenium import webdriver

driver = webdriver.Firefox(executable_path="C:\\path\\to\\geckodriver.exe")
driver.get("https://auth.edgenuity.com/Login/Login/Student")
button = driver.find_element_by_id('LoginSubmit')
button.click()

Answer 2

For what little help it might be, the critical parts of the traceback are

FileNotFoundError: [WinError 2] The system cannot find the file specified

line 3, in <module>
driver = webdriver.Firefox()

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' 
executable needs to be in PATH.

It seems that the Firefox webdriver isn't in the defined search path that your main program sees. There's something called geckodriver that isn't available.

Check your installation and configuration for this package. Consult with your class instructors and classmates for help. I suspect that the repair is something with your local set-up, beyond our knowledge here.
