Scrapy AttributeError:“XmlExportPipeline”对象没有属性“exporter”

Question

我一直在尝试使用Scrapy，并尝试使用这个scraper for football data-https://github.com/hugomathien/football-data-collection来了解更多关于它的信息

现在，除了导出数据之外，所有操作都正常。在

我一直收到这个错误。在

ERROR: Error caught on signal handler: <bound method XmlExportPipeline.spider_closed of <footballData.pipelines.XmlExportPipeline object at 0x1031c0ac8>>
Traceback (most recent call last):

我不会复制完整的代码来节省空间-可以在这里看到-https://github.com/hugomathien/football-data-collection/blob/master/footballData/footballData/pipelines.py

到目前为止，我还没有找到确切的错误，但这可能是由于扭曲的模块还是pydispatch造成的？
