确定已经成功安装了scrapy
进入到存放项目的目录，执行命令
python3 -m scrapy startproject Tencent
输出结果
New Scrapy project ‘Tencent’, using template directory ‘/usr/local/lib/python3.6/site-packages/scrapy/templates/project’, created in:
/root/Tencent
You can start your first spider with:
cd Tencent
scrapy genspider example example.com
表示创建成功，因为我同时安装了python2和python3，如果你的只装了python3
也可以直接执行命令
scrapy startproject Tencent
也会有相同的结果
