模块未发现错误：部署到抓取中心时没有名为'itemloaders'的模块？

Question

我正试图将我的spider部署到抓取集线器，但我的一个导入一直遇到这个错误。这在开发中运行得非常好，只是当我试图部署到刮擦集线器时不行。

从item_loaders.py:导入

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

好吧，我想明白了，我忘了把itemloaders模块添加到我的requirements.txt中，比如：

itemloaders==1.0.4
