Scrapy运行项目时出错：Scrapy 0.16.2 – no active project，Unknown command: crawl，Use "scrapy" to see

Posted 2020-10-18 5K小码

【问题】

通过Scrapy创建好了项目：

1	E:\Dev_Root\python\Scrapy>scrapy startproject songtaste

运行项目，结果出错：

1 2 3 4 5 6

E:\Dev_Root\python\Scrapy>scrapy crawl songtaste -t json -o h1user.json Scrapy 0.16.2 - no active project   Unknown command: crawl   Use "scrapy" to see available commands

【解决过程】

1.参考：

Trying to get Scrapy into a project to run Crawl command

然后才知道，原来是需要切换到对应的项目所在文件夹，再运行crawl，才可以的。

2.所以去，切换到项目所在目录songtaste子文件夹中，再运行，就可以了：

【总结】

虽然此错误，很低级，但是，由于新接触Scrapy，由于不太熟悉，所以还是很容易犯的。
