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

来源:转载

【问题】

通过Scrapy创建好了项目:

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

运行项目,结果出错:

123456E:/Dev_Root/python/Scrapy>scrapy crawl songtaste -t json -o h1user.jsonScrapy 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。
