安装参考博客：http://davenzhang.com/scrapy_install.htm
我是先安装了scrapy，发现import scrapy 的时候报错。之后一次安装了下面关联软件的.exe文件。之后就可以导入了。
- Twisted: twisted-Download
- zope.interface: zope.interface-Download
- lxml: lxml-Download
- pyOpenSSL: pyopenssl-Download
这时候 import scrapy 的时候很正常，但是用scrapy startproject demo 的时候报错了，看version 也报错
D:\Just4Study\Python\TestProgram>C:\Python27\Scripts\scrapy version
Traceback (most recent call last):
File "C:\Python27\lib\runpy.py", line 162, in _run_module_as_main
"__main__", fname, loader, pkg_name)
File "C:\Python27\lib\runpy.py", line 72, in _run_code
exec code in run_globals
File "C:\Python27\lib\site-packages\scrapy\cmdline.py", line 5, in <module>
import pkg_resources
ImportError: No module named pkg_resources
顺着错误找到解释说是没有安装setuptools或者没有装好。搜寻到安装方法：
先下载：
wget http://peak.telecommunity.com/dist/ez_setup.py
再安装
python ez_setup.py
D:\Just4Study\Python\TestProgram>python ez_setup.py

之后运行

安装w3lib去（https://github.com/scrapy/w3lib）下载，安装

这回终于和http://doc.scrapy.org/en/latest/intro/tutorial.html 上描述的一致了。
到这里，我想是安装好了。
