- 在安装Twisted之前,先确定你的pythonb版本,比如我的版本为python3.6.4,那我就该选cp36的,如果你的电脑是64位系统,win_amd64安装失败,可再安装win32的试一下,
- 因为我的64位系统就是安装的win32
pip install C:\Users\CR\Downloads\Twisted-17.5.0-cp36-cp36m-win_amd64.whl
- 5.安装Scrapy
- pip install Scrapy
- 6.Scrapy运行
- 在D盘下新建一个pycodes文件夹,打开cmd
D:\pycodes>scrapy startproject python123demo - New Scrapy project ‘python123demo‘, using template directory ‘c:\\users\\jing\\appdata\\local\\programs\\python\\python36-32\\lib\\site-packages\\scrapy\\templates\\project‘, created in:
