尝试创建webdriver并出现错误

Question

我正在尝试创建Firefox WebDriver，但使用时在python中收到以下错误消息

from selenium import webdriver
driver = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')
driver.get('http://inventwithpython.com')

我收到以下错误：

C:\Users\Kyle\AppData\Local\Programs\Python\Python38-32\python.exe "C:/Users/Kyle/PycharmProjects/pythonProject/Datafolks/smoke tests.py"

During handling of the above exception, another exception occurred:
