Question

我正在尝试使用selenium来处理使用JavaScript代码的某些网站。首先，我使用如下的简单示例

from selenium import webdriver

browser = webdriver.Firefox()

browser.get('http://www.yahoo.com')

browser.quit()

虽然这甚至不起作用。错误消息如下所示。我想我可能会错过硒或其他东西。你能给我一些启示吗？

Traceback (most recent call last):
  File "/home/rnie/webdriver-tutorial-1x.py", line 3, in <module>
    browser = webdriver.Firefox()
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/firefox/webdriver.py", line 145, in __init__
    keep_alive=True)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 92, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 179, in start_session
    response = self.execute(Command.NEW_SESSION, capabilities)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/webdriver.py", line 236, in execute
    self.error_handler.check_response(response)
  File "/usr/lib/python3.5/site-packages/selenium/webdriver/remote/errorhandler.py", line 192, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: connection refused

我检查了"geckodriver.log"，它显示以下错误消息：

1479623778556   geckodriver INFO    Listening on 127.0.0.1:49723

Pl检查路径或者如果您在Linux上查看http://www.linuxquestions.org/questions/linux-server-73/can't-open-display-no-protocol-specified-using-gdm-4175462031 /

Answer 2

随着Selenium 3.0的发布，Firefox Selenium驱动程序已更新为名为Marionette或＆＃34; geckodriver＆＃34;的新驱动程序。这是您系统上的单独二进制文件。

了解如何在Python中使用geckodriver：Selenium install Marionette webdriver

如果您想使用旧的Selenium驱动程序，版本2.x：

Install your Python packages properly using virtual environment
pip install "selenium<3"
将您的Firefox降级到版本45或将firefox版本45二进制文件添加到您的``PATH```环境变量

Answer 3

目前Firefox对Selenium网络驱动程序效果不佳我可以建议您改用Chrome驱动程序

下载chrome驱动程序并解压缩文件。在环境路径中设置chrome驱动程序路径，然后将 Firefox（）替换为Chrome（），尝试使用相同的代码或按照以下代码....

from selenium import webdriver

Path = ("c://chromedriver//chromedriver.exe")
browser = webdriver.Chrome(path)
#eliminate above two steps if the path is set in Environment variable 

browser = webdriver.Chrome() 

browser.get('http://www.yahoo.com')

browser.quit()
