铁杆新手。我遇到了可怕的“语法错误，意外的$ end，期待关键字_end”
但是当我通过
运行时ruby -wc sessionscontroller.rb
它说“语法正常”。我错过了什么？
以下是代码：
class SessionsController < ApplicationController
def create
auth = request.env["omniauth.auth"]
user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) ||
User.create_with_omniauth(auth)
session[:user_id] = user.id
redirect_to root_url, :notice => "Signed in!"
end
end
这是直接来自railscast的copypasta，我很困惑为什么它不起作用。谢谢！
编辑2：确切的消息：
SessionsController中的SyntaxError #create
C:/Users/xxx/Sites/test.yyyy/app/models/user.rb:8: syntax error, unexpected $end, expecting keyword_end
