由于墙的原因,官方的源下载速度极慢.先修改下载源为阿里云的镜像.
首先 win+R 调出运行框,输入%appdata% ,打开程序配置目录,新建pip文件夹,在文件夹下创建pip.ini文件,输入以下内容:
[global]
trusted-host = mirrors.aliyun.com
index-url = http://mirrors.aliyun.com/pypi/simple如下图所示:
接下来安装Numpy,matplotlib,pandas模块.
打开命令行（管理员权限，下同）,输入如下命令安装
pip2 install numpy
pip2 install matplotlib
pip2 install pandas(本应是pip,因本机装了多版本Python,需要为Python2.7安装模块,故输入pip2,
详见:https://zhuanlan.zhihu.com/p/24515742)
(一般情况下够用了，但是某些情况下会报错，比如我在画‘kde’图–核密度估计–的时候，还是报了错，应该是由包与包之间的不兼容造成的。稳妥点的办法是上http://www.lfd.uci.edu/%7Egohlke/pythonlibs/ 按自己的python版本找到对应的whl文件下载下来，然后使用
pip2 install XXXX.whl 安装)
如果安装没问题,到此就结束了.但我在安装时报错,省略其他无用信息,主要错误为:
UnicodeEncodeError: ‘ascii’ codec can’t encode character u’\u258f’ in position 8: ordinal not in range(128)
解决方法如下:
打开Python安装目录,进入Lib/site-packages文件夹,创建sitecustomize.py文件,内容如下:
import sys
reload(sys)
sys.setdefaultencoding('utf-8') 再次在cmd窗口输入安装命令安装.这次安装成功,但窗口输出日志为乱码.
日志如下:
C:\WINDOWS\system32>pip2 install pandas

估计是控制台使用的编码为gbk|gb2312引起的,不影响使用,所以不去管它了.完工,开启用Python做数据分析之路.

补充一个安装ipython的方法。
直接安装是会报错的。一定要先安装pyreadline：
pip2 install pyreadline
pip2 install Jinja2
pip2 install pyzmq
pip2 install tornado
pip2 install sympy
pip2 install ipython
