运行python flask-ask时出现错误

Question

我正在尝试运行memory_game脚本来测试flask-ask，但是每当我尝试从命令行运行脚本时，都会出现相同的错误。我已经安装了所有必需的软件包，但得到的是相同的东西。

[HttpPost]
public async Task<ActionResult> PostBookList(BookListBinding binding)
{
    var bookList = new BookList
    {
        Id = binding.BookId,
        Title = binding.Title 
    });

    var storeList = new StoreList
    {
       Id = binding.StoreId,
       BookId = binding.BookId
    }

    // you work with _context

    return CreatedAtAction("GetBookList", new { id = binding.BookId }, bookList);
}

我希望烧瓶询问能够运行，但是却得到了。有什么需要的吗？

import logging

from random import randint

from flask import Flask, render_template

from flask_ask import Ask, statement, question, session


app = Flask(__name__)

logging.getLogger("flask_ask").setLevel(logging.DEBUG)


@ask.launch

    welcome_msg = render_template('welcome')

    return question(welcome_msg)


@ask.intent("YesIntent")

def next_round():

    numbers = [randint(0, 9) for _ in range(3)]

    round_msg = render_template('round', numbers=numbers)

    session.attributes['numbers'] = numbers[::-1]  # reverse

    return question(round_msg)


@ask.intent("AnswerIntent", convert={'first': int, 'second': int, 'third': 
  int})

def answer(first, second, third):

   winning_numbers = session.attributes['numbers']

   if [first, second, third] == winning_numbers:

       msg = render_template('win')

   else:

       msg = render_template('lose')

   return statement(msg)


if __name__ == '__main__':

   app.run(debug=True)
