Selenium不能与Firefox或Chrome一起使用。

Question

我正在尝试学习Python网络爬虫，但无法让Selenium与任何浏览器配合使用。

from selenium import webdriver
browser = webdriver.Firefox()

这是我拥有的所有代码，但我遇到了错误。

Traceback (most recent call last):
  File "C:\Users\tjhall\AppData\Local\Programs\Python\Python35-32\lib\site-packages\selenium\webdriver\common\service.py", line 64, in start
    stdout=self.log_file, stderr=self.log_file)

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

During handling of the above exception, another exception occurred:

    browser = webdriver.Firefox()

    if self.process is None:

我已尽我所能在互联网上找到的所有方法，包括将路径添加到代码中。

from selenium import webdriver
browser = webdriver.Firefox("C:\Program Files (x86)\Mozilla Firefox\firefox.exe")

将它添加到我的环境变量路径中。我似乎无法弄清楚这一点...

看起来是重复的问题，类似于https://dev59.com/hlkS5IYBdhLWcg3wNkH6 - saurabh baid

Answer 1

现在，无论是 Firefox 还是 Chrome，您都需要下载 geckodriver / chromedriver。这些驱动程序对于在您安装的浏览器和 Selenium 之间进行通信是必要的。因此，您需要：

• 为 Python 安装 Selenium（pip install selenium）
• 下载您想要使用的浏览器的驱动程序（chromedriver、geckodriver、operadriver 等）
• 在您的系统上安装要使用的浏览器（可能已经有了）

现在，您可以像这个 答案 中所提到的那样将 geckodriver 添加到您的路径中。或者，您可以直接在代码中进行设置，如下所示：

Chome: driver = webdriver.Chrome(executable_path='/path/to/chromedriver.exe')

Firefox: driver = webdriver.Firefox(executable_path='/opt/geckoDriver/geckodriver.exe')

我已经根据您提供的信息使其正常工作了。谢谢。 - AutomateMyJob

我尝试了很多不同的方法来安装Selenium，但仍然一直出现错误：FileNotFoundError Traceback (most recent call last) ~\Anaconda3\lib\site-packages\selenium\webdriver\common\service.py in start(self) 75 stderr=self.log_file, ---> 76 stdin=PIPE) 77 except TypeError: - Steve Gon

Answer 2

根据您消息中的行。

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

你没有geckodriver.exe。你需要从这里输入链接描述下载它，将exe放在Python脚本所在的目录中，然后尝试下面的代码：

请尝试此代码：

# -*- coding: utf-8 -*-

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

gecko = os.path.normpath(os.path.join(os.path.dirname(__file__), 'geckodriver'))
binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\firefox.exe')
browser = webdriver.Firefox(firefox_binary=binary,executable_path=gecko+'.exe')
browser.get('http:///www.google.com')
browser.close()
