使用ASK-SDK v2的DynamoDB表创建错误

我是Alexa技能开发新手,从v1到v2迁移时遇到问题。 我的技能是使Alexa记住我使用DynamoDB存储个人物品的位置。基本上就像库存。

我正在使用ask-sdk标准软件包和node js 8.10

我使用.withTableName('PlacesandThings')和.withAutoCreateTable(true)创建表。这是正确的方法吗?我在下面粘贴我的Lambda处理程序

const skillBuilder = Alexa.SkillBuilders.standard();
exports.handler = skillBuilder
  .addRequestHandlers(LaunchRequestHandler,
                      AddThingsIntentHandler,
                      TellIntentHandler,
                      HelpIntentHandler,
                      CancelAndStopIntentHandler,
                      SessionEndedRequestHandler,
    )
    .addErrorHandlers(ErrorHandler)
    .withTableName('PlacesandThings')
    .withAutoCreateTable(true)
    .lambda();

我什至无法发动这项技能。我得到的错误如下

{
  "errorMessage": "skillBuilder.addRequestHandlers(...).addErrorHandlers(...).withTableName is not a function",
  "errorType": "TypeError",
  "stackTrace": [
    "Module._compile (module.js:652:30)",
    "Object.Module._extensions..js (module.js:663:10)",
    "Module.load (module.js:565:32)",
    "tryModuleLoad (module.js:505:12)",
    "Function.Module._load (module.js:497:3)",
    "Module.require (module.js:596:17)",
    "require (internal/module.js:11:18)"
  ]
}

我已经配置了两个Intent:AddThingsIntent将值添加到表中,TellIntent则提醒用户项目存储在何处。意向处理程序如下

const AddThingsIntentHandler = {
    canHandle(handlerInput) {
        return handlerInput.requestEnvelope.request.type === 'IntentRequest'
            && handlerInput.requestEnvelope.request.intent.name === 'AddThingsIntent';
    },
    handle(handlerInput) {
        var ThingName = handlerInput.requestEnvelope.request.intent.slots.ThingName.value;
        var PlaceName = handlerInput.requestEnvelope.request.intent.slots.PlaceName.value;
        const attributes = handlerInput.attributesManager.getSessionAttributes();
        if(attributes.Place === undefined){
            attributes.Place = {};
        }
        attributes.Place[ThingName] = PlaceName;
        const speechText = "I will remember that your " + ThingName + "is/are in/on your " +PlaceName;
        return handlerInput.responseBuilder
            .speak(speechText)
            .reprompt(speechText)
            .withSimpleCard('Reminder Skill', speechText)
            .getResponse();
    }
};
const TellIntentHandler = {
    canHandle(handlerInput) {
        return handlerInput.requestEnvelope.request.type === 'IntentRequest'
            && handlerInput.requestEnvelope.request.intent.name === 'TellIntent';
    },
    handle(handlerInput) {
        var speechText = "";
        var ThingName = handlerInput.requestEnvelope.request.intent.slot.ThingName.value;
        const attributes = handlerInput.attributesManager.getSessionAttributes();
        if(attributes.Place[ThingName]) {
            speechText = 'Your' + ThingName + 'is/are in/on ' +attributes.Place[ThingName];
        }
        else {
            speechText = "I don't know where your " +ThingName + "is/are";
        }
         return handlerInput.responseBuilder
            .speak(speechText)
            .reprompt(speechText)
            .withSimpleCard('Reminder Skill', speechText)
            .getResponse();
    }
};

我已经在DynamoDB中手动添加了表,并且也尝试过。我应该使用DynamoDB持久性适配器吗?我现在应该怎么办?欢迎任何帮助。
