Question

我正在使用python IDLE，在执行以下操作后，我收到此导入错误

>>> from selenium import webdriver
>>> browser=webdriver.Firefox()


Traceback (most recent call last):
  File "C:\Users\saish\AppData\Local\Programs\Python\Python35-32\lib\site-packages\selenium\webdriver\common\service.py", line 74, in start

During handling of the above exception, another exception occurred:

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

Answer 1

您的例外情况很明确：

WebDriverException：消息：＆＃39; geckodriver＆＃39;可执行文件需要在 PATH。

您必须指定geckodriver的路径：

driver = webdriver.Firefox(executable_path=r'/patToYour/geckodriver')

使用Selenium打开浏览器时获取异常
