twisted.internet.error.ReactorAlreadyInstalledError: reactor already installed

Question

I am having this error when I run a crawl process multiples times. I am using scrapy 2.6 This is my code:

from scrapy.crawler import CrawlerProcess
from football.spiders.laliga import LaligaSpider
from scrapy.utils.project import get_project_settings

process = CrawlerProcess(settings=get_project_settings())
for i in range(1, 29):
    process.crawl(LaligaSpider, **{'week': i})
process.start()

Answer 1

For me this worked, I put it before the CrawlerProcess

import sys    
if "twisted.internet.reactor" in sys.modules:
    del sys.modules["twisted.internet.reactor"]
