下载：selenium 3.0.2 : Python Package Index

浏览器驱动：

• Downloads - ChromeDriver - WebDriver for Chrome
• chromedriver.storage.googleapis.com/index.html?path=2.21/
• ```

  coding:utf-8

import star from selenium import webdriver

browser = webdriver.Chrome() browser.get(‘http://www.baidu.com/’)

运行后提示错误：

D:\Python27\python.exe F:/PycharmProjects/test/seleniumStudy.py Traceback (most recent call last): File “F:/PycharmProjects/test/seleniumStudy.py”, line 6, in browser = webdriver.Chrome() File "D:\Python27\lib\selenium\webdriver\chrome\webdriver.py", line 61, in __init__ self.service.start() File "D:\Python27\lib\selenium\webdriver\common\service.py", line 69, in start os.path.basename(self.path), self.start_error_message) selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH.

Exception AttributeError: “‘Service’ object has no attribute ‘process’” in <bound method Service.del of <selenium.webdriver.chrome.service.Service object at 0x02AE3510» ignored

Process finished with exit code 1 ``` 说明是浏览器驱动器没有安装，点击上面的网址安装谷歌浏览器的驱动器，并设置好驱动器的路径到环境变量PATH中去。 我因为之前设置过Python的环境变量：D:\Python27，所以这里直接把下载的chromedriver.exe复制到D:\Python27目录下即可，不用额外再设置了。

再次执行脚本，发现谷歌浏览器新开了一个窗口并打开了百度的网址。
