python - browser = webdriver.Chrome() 不起作用

Question

我正在开始使用 Selenium for python 并有这个:

from selenium import webdriver
browser = webdriver.Chrome()

但是它给出了这个错误:

Traceback (most recent call last):
File "C:\Users\Bradley Jo\AppData\Local\Programs\Python\Python36\lib\site-
packages\selenium\webdriver\common\service.py", line 74, in start
stdout=self.log_file, stderr=self.log_file)

Jo\AppData\Local\Programs\Python\Python36\lib\subprocess.py", line 997, in 
_execute_child
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 "C:\Users\Bradley Jo\Desktop\Project\app.py", line 3, in 
 <module>

  File "C:\Users\Bradley Jo\AppData\Local\Programs\Python\Python36\lib\site-

有人知道如何解决这个问题吗？谢谢

Answer 1

对于 Windows:

1. Check you have installed latest version of chrome browser
2. If not, install latest version of chrome
3. download the latest(or appropriate) version of chromedriver from here
4. Paste the chromedriver.exe file in "<Install Dir>/Python27/Scripts" Folder.

下面的代码现在应该可以工作:

    from selenium import webdriver
    driver = webdriver.Chrome()
