selenium模块下载
在Python中，我们通过pip来下载使用：
pip install selenium
pip install -i https://pypi.doubanio.com/simple/ selenium # 备用地址浏览器驱动下载
除此之外，我们还需要安装浏览器驱动，比较常见的浏览器我们一般选用Chrome和Firefox了，当然IE和Safari也有自己的驱动：
- Chrome驱动地址：https://npm.taobao.org/mirrors/chromedriver，或者参见http://chromedriver.storage.googleapis.com/index.html
- firefox驱动地址：https://github.com/mozilla/geckodriver/releases
- IE驱动地址：https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
- Safari驱动地址：https://webkit.org/blog/6900/webdriver-support-in-safari-10/
根据系统平台下载对应的浏览器驱动，windows下32位即可：
我们下载浏览器驱动的时候，要注意驱动和浏览器的版本对照，一般在每个版本详情目录中的notes.txt文件里，存着对应版本关系：
或者参考下面的对应表：

下载到本地之后，把chromedriver.exe移动至Python解释器同级的目录或者Scripts目录下即可。
测试
现在让我们新建一个test1.py文件，输入如下代码，并运行测试：
from selenium import webdriver
# 创建Chrome WebDriver实例，此路径为驱动程序的路径
driver = webdriver.Chrome()
# firefox浏览器打开
# driver = webdriver.Firefox() # 加载URL网页 driver.get("http://www.baidu.com/") # 打印当前页面的title属性内容 print(driver.title) # 关闭浏览器 driver.quit()可以看到打开一个浏览器，然后很快就关闭了，本地也打印出了结果，表示安装成功！
