Question

所以我正在使用这个社交宝石但由于某种原因我收到以下错误：

wrong number of arguments (1 for 0)

这是导致错误的代码行：

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

不确定我做错了什么，我已经非常彻底地阅读了有关宝石的文档。

我已经花了最近两周的时间，没有运气......无论谁能提供帮助都会非常感激。

Answer 1

从tweet_button移除PreorderHelper方法，因为它覆盖了tweet_button gem的social-buttons方法。

Answer 2

您在tweet_button模块中使用自己的实现覆盖了该gem提供的PreorderHelper方法。覆盖方法不带任何参数，因此，您看到wrong number of arguments: 0 for 1错误。
