我无法弄清楚出了什么问题。

源代码可用，所以我不会混淆这个页面： https://bitbucket.org/davidhughes85/brand_new/src

Answer 1

我猜测，虽然代码的链接已经过时 - exercise sign_in API看起来像这样：

def sign_in(user, options={})
  if options[:no_capybara]
    # Sign in when not using Capybara.
    remember_token = User.new_remember_token
    cookies[:remember_token] = remember_token
    user.update_attribute(:remember_token, User.hash(remember_token))
  else
    visit signin_path
    fill_in "Email",    with: user.email
    fill_in "Password", with: user.password
    click_button "Sign in"
  end
end

错误消息显示wrong number of arguments (2 for 1)中有sign_in。并且因为接受两个参数的唯一一行（假设before { sign_in user, no_capybara: true }）是user.update_attribute，并且在练习页面中也有user.update_attributes接收一个参数，我的钱就在你身上错字：

def sign_in(user, options={})
  if options[:no_capybara]
    # Sign in when not using Capybara.
    remember_token = User.new_remember_token
    cookies[:remember_token] = remember_token
    user.update_attributes(:remember_token, User.hash(remember_token)) # <== TYPO
  else
    visit signin_path
    fill_in "Email",    with: user.email
    fill_in "Password", with: user.password
    click_button "Sign in"
  end
end

您的环境不了解您的功能，可能是您在运行某些测试运行时编写的（不知道是否真实），尝试使用
{{1重置测试环境这应该解决你的问题，希望它可以帮助有同样问题的人。

我遇到了同样的问题。我花了一段时间才找到它，但问题出在utilities.rb文件中。查看方法def sign_in(user, options={ })

问题在于您可能写过：

def sign_in(user, options={ })
  if options[:no_capybara]
    # Sign in when not using Capybara
    remember_token = User.new_remember_token
    cookies[:remember_token] = remember_token
    user.update_attributes(:remember_token, User.digest(remember_token))
  else
    visit signin_path
    fill_in "Email",     with: user.email
    fill_in "Password",  with: user.password
    click_button "Sign in"
  end
end

你应该写：

def sign_in(user, options={ })
  if options[:no_capybara]
    # Sign in when not using Capybara
    remember_token = User.new_remember_token
    cookies[:remember_token] = remember_token
    user.update_attribute(:remember_token, User.digest(remember_token))
  else
    visit signin_path
    fill_in "Email",     with: user.email
    fill_in "Password",  with: user.password
    click_button "Sign in"
  end
end

区别在于您已在if区块user.update_attributes(...)中撰写。你应该写user.update_attribute(...)。这是一个意外多元化方法调用的问题。
