python - 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/Edgenuity Bot"

During handling of the above exception, another exception occurred:

executable needs to be in PATH. 


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()
