Error: Could not load spiders.

Followed the quickstart directions in the readme, these are the results.

iex -S mix run -e "Crawly.Engine.start_spider(BooksToScrape)"

Results:

I have same issue, do you have any update on this?

[oltarasenko]

Hey @3even and @caanmert, the messages above reflect the fact that Crawly tried to load YML spiders from the default folder (which, as I recall, is ./spiders), but because of the fact that it did not find the folder, it just left a debug message about it.

It should not prevent you from any work you plan to do, of course, if you are not trying to use YML spiders as described here: https://www.erlang-solutions.com/blog/effortlessly-extract-data-from-websites-with-crawly-yml/

However, as I see, these messages are confusing for people, so I will hide them when the dynamic spiders folder is not set explicitly.

Sorry for any possible inconveniences.

I've been meaning to submit a PR for it — https://github.com/elixir-crawly/crawly/discussions/270

@dogweather Looks like it's not enough. Probably error messages (even debug), make people think that Crawly is broken and no spiders will run :(. So I think it's better to hide it completely unless enabled.

I think the debug message we have now, looks quite ok:

12:57:29.967 [info] No spiders found to auto-load: %MatchError{term: {:error, :enoent}}
