Scrapy：无法将 json 导出到 csv

Question

我有这个脚本：

    import scrapy
    from scrapy.crawler import CrawlerProcess
    from datetime import datetime
    import os
    
    
    if os.path.exists('jfs_hombre.csv'):
        os.remove('jfs_hombre.csv')
        print("The file has been deleted successfully")
    else:
        print("The file does not exist!")
    
    
    class JfsSpider_hombre(scrapy.Spider):
        name = 'jfs_hombre'
        #start_urls = ["https://www.justforsport.com.ar/hombre?page=1"]
            
        def start_requests(self):
    
            yield scrapy.Request(
                url='https://www.justforsport.com.ar/_v/segment/graphql/v1?workspace=master&maxAge=short&appsEtag=remove&domain=store&locale=es-AR&__bindingId=e841e6ce-1216-4569-a2ad-0188ba5a92fc&operationName=productSearchV3&variables=%7B%7D&extensions=%7B%22persistedQuery%22%3A%7B%22version%22%3A1%2C%22sha256Hash%22%3A%226869499be99f20964918e2fe0d1166fdf6c006b1766085db9e5a6bc7c4b957e5%22%2C%22sender%22%3A%22vtex.store-resources%400.x%22%2C%22provider%22%3A%22vtex.search-graphql%400.x%22%7D%2C%22variables%22%3A%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%22%7D',
                callback=self.parse,
                method="GET"
            )
    
        def parse(self, response):
            resp = response.json()
            #print(resp)
            for item in range(0,576,32):
                resp['recordsFiltered']=item
           
                for result  in resp['data']['productSearch']['products']:
                    yield {
                        'Casa':'Just_For_Sports',
                        'Sku' :result['productReference'],
                        'Name': result['productName'],
                        'precio': result['priceRange']['sellingPrice']['highPrice'],
                        'Link': result['link'],
                        'Date':datetime.today().strftime('%Y-%m-%d')
    
                    }
    
    
    process= CrawlerProcess(
        settings = { 
            'FEED_URI':'jfs_hombre.csv' ,
            'FEED_FORMAT': 'csv',
            'FEED_EXPORT_ENCODING':'utf-8',
            } )   

if __name__ == "__main__":
    process =CrawlerProcess()
    process.crawl(JfsSpider_hombre)
    process.start()

这是我第一次使用 Call Api，Json...所以我对此一无所知，但我一直在使用 scrapy。问题是我无法获取 .csv ，它没有创建任何文件...抓取器工作正常，我获取了所有数据，但无法导出...我做错了什么？？

提前致谢！
