python-2.7 - 如何在ubuntu上安装scrapy？

Question

我知道安装scrapy应该先安装w3lib，所以我先安装w3lib，但是当我在python ide中导入scrapy时，程序崩溃了。

怎么了？

Answer 1

这是我在ubuntu上安装scrapy的方式:

sudo apt-get update
sudo apt-get install python-pip build-essential python-dev libxslt-dev libxml2-dev   
sudo -H pip install Scrapy
scrapy version

解决我的问题的重要事情是 sudo -H pip install Scrapy特别是 -H旗帜。

我也退出了终端并启动了一个新终端以确保正确设置了所有环境变量
