你可以在这里发布完整的'user.rb'文件吗？ –

可能的错误在于，您在模型中的'validates'指令中省略了''';你需要'验证：参数，唯一性：{x：y}，presence：true'（注意逗号） –

确保您user.rb文件看起来正是这样的：

class User < ActiveRecord::Base 
    before_save { self.email = email.downcase } 
    validates :name, presence: true, length: { maximum: 50 } 
    VALID_EMAIL_REGEX = /\A[\w+\-.][email protected][a-z\d\-.]+\.[a-z]+\z/i 
    validates :email, presence: true, length: { maximum: 255 }, 
        format: { with: VALID_EMAIL_REGEX }, 
        uniqueness: { case_sensitive: false } 
    has_secure_password 
    validates :password, presence: true, length: { minimum: 6 } 
end

错误消息告诉你，你user.rb有一个语法错误：

SyntaxError: /app/models/user.rb:6: syntax error, unexpected ':', expecting keyword_end 
format: { with: VALID_EMAIL_REGEX } 
    ^
/app/models/user.rb:7: syntax error, unexpected ':', expecting keyword_end 
uniqueness: { case_sensitive: false }

您可能错过了,或关闭}。

重新访问您的user.rb（特别是第5-7行），并仔细检查它是否与example in the book完全一样。
