Ubuntu 12.04 安装Scrapy爬虫框架

亲测有效

根据Scrapy安装指南(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.

进入这个页面(http://doc.scrapy.org/en/latest/topics/ubuntu.html#topics-ubuntu)

为了安装这个packages,在ubuntu下运行 lsb_release -cs,显示

现在需要做的就是用vi添加 deb http://archive.scrapy.org/ubuntu precise main 到 /etc/apt/sources.list中去

然后运行 curl -s http://archive.scrapy.org/ubuntu/archive.key | sudo apt-key add - 

再更新源 sudo apt-get update

最后安装  sudo apt-get install scrapy-0.1X
可选择不同版本，我安装的是0.16
