我换 linux 环境现在可以运行了，运行$ python doubanSpider.py 后一直在下载，是什么意思额？
/usr/local/lib/python2.7/dist-packages/bs4/__init__.py:166: UserWarning: No parser was explicitly specified, so I'm using the best available HTML parser for this system ("html.parser"). This usually isn't a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.

To get rid of this warning, change this:

BeautifulSoup([your markup])

to this:

BeautifulSoup([your markup], "html.parser")

首先要安装 python ，到 python.org 上下载安装，然后双击运行 python 文件或者 python ***.py

@niboy 安装了双击一闪而过，改名成 doubanSpider.pyw 用 IDLE 打开后，运行 run module 提示 Traceback (most recent call last):
File "C:\Users\lenovo\Desktop\DouBanSpider-master\doubanSpider.pyw", line 7, in <module>
import requests
ImportError: No module named requests

@grey5659
你缺少 requests 依赖包。。 http://blog.csdn.net/alpha5/article/details/24964009

其他的，你自己想办法解决吧，比如下面这些。。
import numpy as np
from bs4 import BeautifulSoup
from openpyxl import Workbook

安装 python2.7 然后 cmd 运行 pip install requests ，省事的话就虚拟个 ubuntu 去运行，不然 windows 各种 bug 让你抓狂

没什么大问题，就是 beautifulsoup 这个库报了个警告，因为没显式指定 html 解析器，爬虫已经在工作了
