ModuleNotFoundError：部署到抓取集线器时没有名为“itemloaders”的模块？

Question

I'm trying to deploy my spider to scraping hub but I keep running into this error with one of my imports. This works perfectly fine in development, just not when I attempt to deploy to scraping hub.

Import from item_loaders.py:

from itemloaders.processors import Identity, MapCompose, TakeFirst, Join
from w3lib.html import remove_tags
from scrapy.loader import ItemLoader

Welp, I figured it out, I forgot to add the itemloaders module to my requirements.txt like such:

itemloaders==1.0.4
