not a valid language tag

[ToruHyuga]

Hello, I have some problem with sandcrawler Phantom Spider. I tried to use this code:

var sandcrawler = require('sand crawler')
var spider = sandcrawler.phantomSpider()
            .url('https://news.ycombinator.com');
sandcrawler.run(spider, function(error, data) {
    if(error) {
        console.log(error);
    } else {
        console.log(data);
    }
});

And some other examples from here But always had the same error:

events.js:146
throw err;
^

Error: Uncaught, unspecified "error" event. (Fontconfig warning: ignoring C.UTF-8: not a valid language tag
)
at Spy.emit (events.js:144:17)

at readableAddChunk (_stream_readable.js:146:16)

Can someone help me please?
