【問題】
通過Scrapy創建好了項目：
|
1
|
E:\Dev_Root\python\Scrapy>scrapy startproject songtaste
|
運行項目，結果出錯：
|
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
|
【解決過程】
1.參考：
Trying to get Scrapy into a project to run Crawl command
然后才知道，原來是需要切換到對應的項目所在文件夾，再運行crawl，才可以的。
2.所以去，切換到項目所在目錄songtaste子文件夾中，再運行，就可以了：

【總結】
雖然此錯誤，很低級，但是，由於新接觸Scrapy，由於不太熟悉，所以還是很容易犯的。
