selenium:chromedriver与chrome版本的对应关系

Posted 2020-11-01 whist

今天想用Python实现一个自动刷新网页的脚本，需要用到selenium。
因为刚开始没有指定chromedriver，所以报错：

Traceback (most recent call last):
  File "D:\Anaconda3\lib\site-packages\selenium\webdriver\common

\service.py", line 76, in start
    stdin=PIPE)
  File "D:\Anaconda3\lib\subprocess.py", line 709, in __init__
    restore_signals, start_new_session)
  File "D:\Anaconda3\lib\subprocess.py", line 997, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] 系统找不到指定的文件。

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "f5.py", line 5, in <module>
  File "D:\Anaconda3\lib\site-packages\selenium\webdriver\chrome

\webdriver.py", line 68, in __init__

    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: ‘chromedriver‘ 

executable needs to be in PATH. Please see

然后我去下载chromedriver，随便下了一个版本的，结果又报错：

    return self._sock.recv_into(b)
ConnectionResetError: [WinError 10054] 远程主机强迫关闭了一个现有的连接。

之后继续百度寻找答案，才发现：
再使用selenium打开chrome浏览器的时候，需要用chromedriver，而chromedriver与
chrome的版本也是要相互适宜的，对应关系如下：

chromedriver版本	支持的Chrome版本
v2.36	v64-66
v2.35	v62-64
v2.34	v61-63
v2.33	v60-62
v2.32	v59-61
v2.31	v58-60
v2.30	v58-60
v2.29	v56-58

所以，先在浏览器地址栏输入：chrome://version
得到浏览器的版本，之后找到对应的chromedriver版本，并下载。
