wrong number of arguments (1 for 0) (Social Gem )

问题

So I'm using this social gem but for some reason I'm getting the following error:

wrong number of arguments (1 for 0)

and this is the line of code that's causing the error:

   <%= tweet_button(via: "peterc", url: "http://news.ycombinator.com", :text => "AWESOME.")  %>

Not sure what I'm doing wrong, I've read the Documentation on the gem quite thoroughly.

I've spent the last 2 weeks straight on this, with no luck.. whoever can help would be REALLY appreciated.

Update;

回答1:

Remove tweet_button method from the PreorderHelper as it is overriding the tweet_button method of social-buttons gem.

回答2:

You're overriding the tweet_button method that is supplied by that gem with your own implementation in the PreorderHelper module. The overriding method doesn't take any arguments, and thus, you're seeing the wrong number of arguments: 0 for 1 error.
