ubuntu 下安裝scrapy

1.把Scrapy簽名的GPG密鑰添加到APT的鑰匙環中:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 627220E7

2.執行如下命令，創建 /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.更新包列表並安裝 scrapy-0.25:

sudo apt-get update && sudo apt-get install scrapy-0.25
