我在使用Scrapy执行fetch（url）命令时遇到了这个错误。我使用的是Scrapy 2.7.1，Python 3.10.6和Ubuntu 22.04上的miniconda
以下是我已完成的步骤：

scrapy startproject worldometers

cd worldometers

scrap shell

fetch("https://www.worldometers.info/world-population/population-by-country/")

这是我得到的错误消息：

    current.result = callback(  # type: ignore[misc]

有任何修正错误的建议吗？
目前卡住了，我试着搜索互联网，但仍然没有解决方案
