使用Python脚本运行WebDriver时出错

Question

我在使用库selenium在python中使用脚本运行执行Webdriver时遇到了问题.我发布了示例代码方案以及执行时抛出的相应错误.

代码场景:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")

错误场景:

Traceback (most recent call last):

  File "C:/Users/Kaushik/Desktop/IMC DEVELOPER TEST/Sample.py", line 4, in <module>
    driver = webdriver.Firefox()

  File "C:\Python27\lib\site-packages\selenium-2.37.2-py2.7.egg\selenium\webdriver\firefox\webdriver.py", line 59, in __init__
    self.binary, timeout),

  File "C:\Python27\lib\site-packages\selenium-2.37.2-py2.7.egg\selenium\webdriver\firefox\extension_connection.py", line 47, in __init__
    self.binary.launch_browser(self.profile)

  File "C:\Python27\lib\site-packages\selenium-2.37.2-py2.7.egg\selenium\webdriver\firefox\firefox_binary.py", line 60, in launch_browser
    self._start_from_profile_path(self.profile.path)

  File "C:\Python27\lib\site-packages\selenium-2.37.2-py2.7.egg\selenium\webdriver\firefox\firefox_binary.py", line 83, in _start_from_profile_path
    env=self._firefox_env).communicate()

  File "C:\Python27\lib\subprocess.py", line 709, in __init__
    errread, errwrite)

  File "C:\Python27\lib\subprocess.py", line 957, in _execute_child
    startupinfo)
WindowsError: [Error 87] The parameter is incorrect

我理解错误抛出了.我只需要使用selenium库使用python脚本从网站检索动态数据.

您的代码没有任何问题,它对我来说很好.

你有安装firefox吗？如果没有,您可以使用其他浏览器.例如:

driver = webdriver.Ie 

要么

driver = webdriver.Opera
