Selenium Webdriver无法在Firefox中使用Firefox

Question

我安装了最新的firefox浏览器和硒。 我尝试运行以下代码：

from selenium import webdriver

browser = webdriver.Firefox()

...并收到以下错误：

Traceback (most recent call last):
  File "C:\Users\alisy\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start
    stdin=PIPE)

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

During handling of the above exception, another exception occurred:

    browser = webdriver.Firefox()

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

我已经下载了geckodriver，并在PATH中指定了位置（然后重新启动了笔记本电脑）。 Firefox也一样。 没关系。 我该怎么办？

Answer 1

这行代码为我解决了问题

driver=webdriver.Firefox(executable_path="c:/drivers/geckodriver.exe")
