windows下pip升级到8.1.1 及安装Selenium

1.升级pip

windows CMD

D:\Program Files\Python34\Scripts>pip install --upgrade pip 升级失败，提示尝试替换自身失败
改用

D:\Program Files\Python34\Scripts>easy_install pip 升级到最新版本

Python环境

python -m pip install -U pip

2.安装Selenium

windows CMD

D:\Program Files\Python34\Scripts>pip install selenium

输出：

Requirement already satisfied (use --upgrade to upgrade): selenium in d:\program
files\python34\lib\site-packages

VS建立项目测试：

# -*- coding: utf_8 -*-

import os
from selenium import webdriver

iedriver = "C:\Program Files\Internet Explorer\IEDriverServer.exe"
os.environ["webdriver.ie.driver"] = iedriver

driver = webdriver.Ie(iedriver)
driver.get("http://www.baidu.com")
print(driver.title)
driver.quit()

运行提示：

selenium.common.exceptions.WebDriverException: Message: Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones. Enable Protected Mode must be set to the same value (enabled or disabled) for all zones

修改注册表 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones

修改1、2、3、4文件中2500属性值 修改成相同属性值、如1-2文件中是3，3-4文件中是0，修改3、4中2500属性值为3，重新运行脚本即可打开浏览器
