How to crawl local HTML file with Scrapy

Question

I tried to crawl a local HTML file stored in my desktop with the code below, but I encounter the following errors before crawling procedure, such as "No such file or directory: '/robots.txt'".

• Is it possible to crawl local HTML files in a local computer(Mac)?
• If possible, how should I set parameters like "allowed_domains" and "start_urls"?

[Scrapy command]

$ scrapy crawl test -o test01.csv

[Scrapy spider]

class TestSpider(scrapy.Spider):
    name = 'test'
    allowed_domains = []
    start_urls = ['file:///Users/Name/Desktop/test/test.html']

[Errors]

Answer 1

When working with it locally, I never specify the allowed_domains. Try to take that line of code out and see if it works.

In your error its testing the 'empty' domain that you have given it.
