So as the title says, I'm following Michael Hartl's RoR Book and I'm currently on chapter 9.3 - Showing User. All tests passed before this chapter, I'm following the Rails 4 version of the book and I'm very new to this RoR.
正如标题所说，我正在关注Michael Hartl的RoR Book，我目前正在进行第9.3章 - 显示用户。所有测试都在本章之前通过，我正在阅读本书的Rails 4版本，我对这个RoR很新。

This looks like a template error.
这看起来像模板错误。
One error points towards this file: /app/helpers/users_helper.rb line 4 and it looks like you have the wrong number of arguments in gravatar_for. Then the next place to look is /app/views/users/index.html.erb line 7.
一个错误指向此文件：/app/helpers/users_helper.rb第4行，看起来你在gravatar_for中有错误的参数数量。接下来要看的是/app/views/users/index.html.erb第7行。

I figured it out.
我想到了。
The problem is with the gravatar_for arguments.
问题在于gravatar_for参数。
I made mistake and did not update the gravatar_for method in users_helper that's what is giving this error.
我犯了错误，并且没有更新users_helper中的gravatar_for方法，这就是给出此错误的原因。
def gravatar_for(user, options = { size: 50 })
gravatar_id = Digest::MD5::hexdigest(user.email.downcase)
size = options[:size]
gravatar_url = "https://secure.gravatar.com/avatar/#{gravatar_id}?s=#{size}"
image_tag(gravatar_url, alt: user.name, class: "gravatar")
end
Updated gravatar_for method.
