注：在python3.x 64位版本环境下

一。Scrapy的安装

1.打开网页

http://www.lfd.uci.edu/~gohlke/pythonlibs/

下载一下下面几个文件，用Crtl+F查询

前两个只要下载一个，放在一个文件夹里

2.打开cmd窗口，cd到你存文件的目录

依次执行下列命令，等处理完在输入下一行（后面为你下载的文件名）

pip install wheelpip install lxml-3.7.3-cp36-cp36m-win_amd64.whlpip install Twisted-17.1.0-cp36-cp36m-win_amd64.whlpip install Scrapy-1.3.3-py2.py3-none-any.whl

最后验证

这就安装成功了

二。安装pywin32

1.打开网址

https://sourceforge.net/projects/pywin32/files/pywin32/Build%20221/

下载后直接安装

2.安装错误

出现找不到Python路径，又不能手动输入，新建一个resister.py文件，输入

此文件就是在注册表内注册Python

好了，继续安装就不会报错了，ok

开始。。。
