selenium python2.7安装配置1：安装python
python2.7版本(最新的python版本是3.4，但用户体验没有2.7版本的好，我们选择用2.7版本)
下载地址：https://www.python.org/download/releases/2.7.8/
下载Windows x86 MSI Installer (2.7.8)安装包
设置系统环境变量
执行命令验证
输入Python
2：下载安装setuptools工具集
在命令行方式下，进入目录“C:\Python27\Scripts”，执行python ez_setup.py。
若安装后Scripts文件夹下，没有ez_setup.py
把下面内容复制到记事本，重命名ez_setup.py，记得后缀别错了，否则无效。

也可以：
下载https://bootstrap.pypa.io/ez_setup.py
python ez_setup.py #安装 setuptools
如果还是不能安装：
1.下载windows的压缩包，解压到python安装路径
2.执行命令，python setup.py即可
3：下载pip 【python的安装包管理工具】
https://pypi.python.org/pypi/pip
解压pip包并进入到解压后的文件目录下。
执行python setup.py install
再切换到C:\Python27\Scripts 目录下输入：
C:\Python27\Scripts > easy_install pip
安装完毕之后会在系统目录下生成Scripts目录，里面有 ：
easy_install.exe 和 pip.exe 等可执行文件。
最好，把python和python2.7.5/Scripts添加到系统配置文件path属性值里。
这样就可以直接执行了，
安装完pip和easy_installer工具后，以后再安装python其他库就方便了
例：
easy_install redis
或
pip install redis （推荐使用pip）
本人测试，easy_install 没有问题，但是使用pip就报错了，奇葩了，后来没办法就使用easy_install重新安装了一下：
如果还不行：
下载后，解压缩上面pip-9.0.1.tar.gz文件，打开CMD，进入解压缩后文件的根目录，该目录中有一个setup.py文件，然后再cmd中输入python setup.py install命令
所有安装完成，查看相关文件路径：
看到上图中提示信息，说明你的pip已经安装成功啦，进入Python安装路径的Scripts文件夹下即可看到pip.exe，说明可以使用pip啦，具体如下：
4：安装selenium（验证pip是否安装成功）
在Python安装目录下的Scripts目录下执行pip install -U selenium安装selenium
若未联网也可以下载selenium for python解压后放置在Lib\site-pageages目录下
3.5：下载并安装测试报告文件包
下载HTMLTestRunner.py放置在Lib目录下:
http://tungwaiyip.info/software/HTMLTestRunner.html
3.6.我的第一个程序：
from time import sleep
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver=webdriver.Chrome()
driver.maximize_window()
driver.get("https://www.baidu.com/")
driver.find_element_by_id("kw").send_keys("selenium",Keys.ENTER)
sleep(3)
driver.quit()注意：
chromedriver.exe必须放到system32下，否则脚本不能运行
