根據Scrapy安裝指南(http://doc.scrapy.org/en/latest/intro/install.html)
Don’t use the python-scrapy package provided by Ubuntu, they are typically too old and slow to catch up with latest Scrapy.
Instead, use the official Ubuntu Packages, which already solve all dependencies for you and are continuously updated with the latest bug fixes.
進入這個頁面(http://doc.scrapy.org/en/latest/topics/ubuntu.html#topics-ubuntu)
爲了安裝這個packages,在ubuntu下運行 lsb_release -cs,顯示
現在需要做的就是用vi添加 deb http://archive.scrapy.org/ubuntu precise main 到 /etc/apt/sources.list中去
然後運行 curl -s http://archive.scrapy.org/ubuntu/archive.key | sudo apt-key add -
再更新源 sudo apt-get update
最後安裝 sudo apt-get install scrapy-0.1X
可選擇不同版本，我安裝的是0.16
