1.把Scrapy签名的GPG密钥添加到APT的钥匙环中:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 627220E7
2.执行如下命令，创建 /etc/apt/sources.list.d/scrapy.list 文件:
echo 'deb http://archive.scrapy.org/ubuntu scrapy main' | sudo tee /etc/apt/sources.list.d/scrapy.list
3.更新包列表并安装 scrapy-0.25:
sudo apt-get update && sudo apt-get install scrapy-0.25
