【问题描述】：

我在 Windows pro 10 上并使用 Firefox 来执行 python selenium 程序。尝试运行：

from selenium import webdriver
wb = webdriver.Firefox()
wb.get("https://stackoverflow.com")

出现以下错误（请忽略错误消息中的网络浏览器）：

Traceback (most recent call last):
  File "C:\Users\dilri\AppData\Local\Programs\Python\Python36-32\lib\site-       packages\selenium\webdriver\common\service.py", line 74, 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:

Traceback (most recent call last):
  File "H:\temp.py", line 2, in <module>
    driver = webdriver.Chrome()
  File "C:\Users\dilri\AppData\Local\Programs\Python\Python36-32\lib\site-   packages\selenium\webdriver\chrome\webdriver.py", line 62, in __init__
    self.service.start()

标签： python python-3.x selenium selenium-webdriver

【解决方案1】：

正如错误消息中明确提到的，首先安装适当的浏览器驱动程序并将其路径指定为system variable 路径。就像我的情况一样：

from selenium import webdriver
driver_path = r"G:\Python\geckodriver.exe" #since on windows use raw strings 
wb = webdriver.Firefox(executable_path=driver_path)

# to check if it's working
wb.get("https://stackoverflow.com")

记住：驱动程序路径必须是原始字符串，因为我们在 Windows 上工作。另外，请注意不要将文件名指定为 selenium.py
