我是scrapy的新手，我在scrapy中创建了一个示例项目并运行该项目。我有一个错误

AttributeError: 'module' object has no attribute 'OP_SINGLE_ECDH_USE'

码：

import scrapy
class DmozSpider(scrapy.Spider):
    name = "dmoz"
    allowed_domains = ["dmoz.org"]
    start_urls = ["https://www.grocerygateway.com"]

    def parse(self, response):
        filename = response.url.split("/")[-2]
        with open(filename, 'wb') as f:
            f.write(response.body)

提前致谢
