I have tried to reproduce the code exactly in the url_scraper documentation, but am unable to build the program.

I think it is an error with the cssparser dependency. Any ideas how to fix?

Error:

To Reproduce:

My main.rs is:

extern crate url_scraper;
use url_scraper::UrlScraper;

fn main() {
    let directory = "http://phoronix.com/";

    let scraper = UrlScraper::new(directory).unwrap();
    for (text, url) in scraper.into_iter() {
        println!("{}: {}", text, url);
    }
}

My Cargo.tom dependencies are:

[dependencies]
url-scraper = "0.1.1"

This compile error broke downstream: such as url-crawler. This version bump seems to clear it up.

Referring to this issue I think this might solve compilation issues. I don't anticipate this, but you might wanna double check this doesn't break anything.
