##windows7 安装 Scrapy##

1.打开cmd.exe输入命令:

	C:\Users\admin>python
	先看是否已经安装python,没有就安装python,此处省略安装python。

2.假设已经安装有python,查看是否已经安装好pip

	C:\Users\admin>pip

a. 没有就去下载pip

	网址如下:https://pypi.python.org/pypi/pip#downloads
	下载这个压缩包:pip-9.0.1.tar.gz (md5, pgp)

b. 解压到指定目录,进入pip-9.0.1目录,输入此命令

	python setup.py install

c. 如果出现以下错误:

	Traceback (most recent call last):  
	  File "setup.py", line 31, in <module>  
	    from setuptools import setup, find_packages  
	ImportError: No module named setuptools  

d. 就安装setuptools:

	网址:https://pypi.python.org/pypi/setuptools
	下载这个压缩包:setuptools-38.5.2.zip (md5)

f. 解压到指定目录,进入setuptools-38.5.2目录,输入此命令

	python setup.py install

g. 如果出现以下错误:

    running build_ext
	    building 'twisted.test.raiser' extension
	    error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual
	C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

	网址:https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted

h. 下载二选一:
			Twisted‑17.9.0‑cp36‑cp36m‑win_amd64.whl(看系统位数下载)
			Twisted‑17.9.0‑cp36‑cp36m‑win32.whl(看系统位数下载)

3.安装scrapy

	C:\Users\admin>pip install Scrapy
	成功后提示:
	Installing collected packages: Scrap
	Successfully installed Scrapy-1.5.0

4.如果运行scapy crawl quotes【quotes是项目名字】报错,就安装pypiwin32

     C:\Users\admin>pip install pypiwin32

5.再次运行就会成功
