##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:

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:
