【问题描述】：

我正在尝试创建一个在给定 URL 时刷新任何页面的功能。但是程序不会运行。我究竟做错了什么？这是我的代码：

from selenium import webdriver
import time

def page_refresh(url):
    driver = webdriver.Firefox()
    driver.get(url)
    x = 0
    while x <= 5:
        time.localtime(10)
        driver.refresh(url)
    driver.close

page_refresh('https://www.wikipedia.org/')

这是我得到的：

Traceback (most recent call last):
File "C:\Users\100453649\PycharmProjects\AutoRefresher\venv\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:

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

【问题讨论】：

线索在异常的最后一行。未找到壁虎驱动程序。
堆栈跟踪中的最后一行定义了您的问题。 geckodriver 无法启动。它必须位于包含在PATH 变量中的目录中，或者您必须在启动webdriver 时将路径定义为webdriver 的参数。你安装了geckodriver吗？如果是这样，它在哪里？它是否位于PATH 中定义的目录中？如果是这样，是否设置了权限，以便运行程序的用户可以启动它（可执行）？
WebDriverException: 'geckodriver' executable needs to be in PATH even though it is的可能重复

【解决方案1】：

你的例外清楚地说明了

selenium.common.exceptions.WebDriverException：消息：“geckodriver”可执行文件需要在 PATH 中。

解决方案：

添加壁虎驱动路径：

例子：

 from selenium import webdriver
 driver = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')
 driver.get(url)
