scrapy 2.3 创建项目

在开始抓取之前，你必须建立一个新的零碎项目。输入要在其中存储代码并运行的目录：

scrapy startproject tutorial

这将创建一个 ​tutorial​ 目录包含以下内容：

tutorial/
    scrapy.cfg            # deploy configuration file

    tutorial/             # project's Python module, you'll import your code from here
        __init__.py

        items.py          # project items definition file

        middlewares.py    # project middlewares file

        pipelines.py      # project pipelines file

        settings.py       # project settings file

        spiders/          # a directory where you'll later put your spiders
            __init__.py
