To install globally with pip

$ sudo pip3 install virtualenv

virtual a environment

$ virtualenv ENV     # Where ENV is a directory to place the new virtual environment.

activate script

$ source bin/activate       # or: $ . bin/activate

Inside a virtualenv, you can install Scrapy with pip after that:

pip install scrapy

---------------------------- 在此分割线上已成功安装完 Scrapy 了 ------------------------------

退出虚拟环境,

$ deactivate

删除虚拟环境

$ rm -r /path/to/ENV
