{使用python自动处理无聊的内容}使用selenium / python进行网络抓取

Question

我正在学习python。在使用Selenium进行Web抓取时，python显示chromedriver.exe / geckodriver.exe未添加到PATH的错误。但我已经将它们都添加到了路径中。

代码：

browser = webdriver.Chrome()

错误：

Traceback (most recent call last):
  File "C:\Users\HP\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start
    stdin=PIPE)

During handling of the above exception, another exception occurred:
