Question

我正在使用Python 3开发一个scrapy项目，并将spiders部署到scrapinghub。我还使用Google云端存储来存储官方文档here中提到的已删除文件。

当我在本地运行蜘蛛并且蜘蛛被部署到scrapinghub而没有任何错误时，蜘蛛运行得非常好。我正在使用 scrapy：1.4-py3 作为scrapinghub的堆栈。在运行蜘蛛时，我收到以下错误：

    Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/twisted/internet/defer.py", line 1386, in _inlineCallbacks
    result = g.send(result)

    self.engine = self._create_engine()

    pipe = cls.from_settings(crawler.settings)
  File "/usr/local/lib/python3.6/site-packages/scrapy/pipelines/images.py", line 95, in from_settings
    return cls(store_uri, settings=settings)
  File "/usr/local/lib/python3.6/site-packages/scrapy/pipelines/images.py", line 52, in __init__
    download_func=download_func)
  File "/usr/local/lib/python3.6/site-packages/scrapy/pipelines/files.py", line 234, in __init__
    self.store = self._get_store(store_uri)
  File "/usr/local/lib/python3.6/site-packages/scrapy/pipelines/files.py", line 269, in _get_store
    store_cls = self.STORE_SCHEMES[scheme]
KeyError: 'gs'

PS：'gs'用于存储文件的路径，如

'IMAGES_STORE':'gs://<bucket-name>/'

我已经研究过这个错误，但是没有任何解决方案。任何帮助都会有很大的帮助。

Google Cloud Storage支持是Scrapy 1.5中的一项新功能，因此您需要在Scrapy Cloud中使用scrapy:1.5-py3堆栈。

Scrapy，Scrapinghub和谷歌云存储：在scrapinghub
