webdriver.Chrome()报错：selenium.common.exceptions.WebDriverException: Message: 'chromedriver' ...

使用selenium模块的webdriver打开谷歌浏览器的时候报错。源代码如下:

from selenium import  webdriver
browser = webdriver.Chrome()
print(type(browser))
browser.get('https://www.baidu.com')

错误信息如下：

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Process finished with exit code 1

根据错误提示：Message: 'chromedriver' executable needs to be in PATH我们可以找到原因所在：chromedriver需要放在python安装路径下。

解决办法：

（1）打开提示的链接：https://sites.google.com/a/chromium.org/chromedriver/home（可能需要工具才能访问）

（2）点击Downloads

(3)将解压后得到的chromedriver.exe放到Python安装路径下，如：

最后重新运行即可。

鉴于（1）的链接可能需要工具才能访问，大家可以直接搜索chromedriver到CSDN上下载。
