AWS Lambda:无法导入模块

Question

请原谅我,我是Lambda和Node的全新人物.

我正在尝试复制这个 git,使用AWS IoT按钮订购披萨.

我目前的代码是:

var pizzapi = require('dominos');

var myStore = new pizzapi.Store(
    {
        ID: 'Example'
    }
);

var myAddress = new pizzapi.Address(
        {
            Street: 'Example',
            City: 'Example',
            Region: 'Example',
            PostalCode: 'Example'
        }
    );

var myCustomer = new pizzapi.Customer(
    {
        firstName: 'Example',
        lastName: 'Example',
        address: myAddress,
        phone: 'Example',
        email: 'Example@gmail.com'
    }
);

var order = new pizzapi.Order(
    {
        customer: myCustomer,
        storeID: myStore.ID
    }
);

var cardNumber='Example';
var cardInfo = new order.PaymentObject();
cardInfo.Amount = order.Amounts.Customer;
cardInfo.Number = cardNumber;
cardInfo.CardType = order.validateCC(cardNumber);
cardInfo.Expiration = 'Example';
cardInfo.SecurityCode = 'Example';
cardInfo.PostalCode = 'Example';

order.Payments.push(cardInfo);

function orderDominos(event, context) {
  var clickType = event.clickType;
  switch(clickType.toLowerCase()) {
    case "single": {
      order.addItem(
          new pizzapi.Item(
              {
                  code: 'P_14SCREEN',
                  options: {},
                  quantity: 1
              }
          )
      );
      break;
    }
    case "double": {
        order.addItem(
          new pizzapi.Item(
              {
                  code: 'P_14SCREEN',
                  options: {},
                  quantity: 1
              }
          )
      );
      break;
    }
    case "long": {
        order.addItem(
          new pizzapi.Item(
              {
                  code: 'P_14SCREEN',
                  options: {},
                  quantity: 1
              }
          )
      );
      break;
    }
  }
  order.validate(
      function(result) {
          console.log("Order is Validated");
      }
  );
  order.price(
      function(result) {
            console.log("Order is Priced");
      }
  );
  order.place(
      function(result) {
          console.log("Price is", result.result.Order.Amounts, "\nEstimated Wait Time",result.result.Order.EstimatedWaitMinutes, "minutes");
          console.log("Order placed!");
          context.succeed(event);
      }
  );
}

exports.handler = orderDominos;

文件结构是:

• orderDominos.js
• node_modules /多米诺骨牌

我压缩文件,上传到Lambda,并将标题指向"index.handler"

我究竟做错了什么？

编辑:错误

Answer 1

在我的情况下,我提到Handler,index.handler但我的根文件名是app.js.将此更改为index.js有效.

还要确保zip文件index.js, node_modules and package.json直接存在.

应该:

zip file --> index.js
             package.json
             node_modules

不

zip file --> some_folder_name --> index.js
                                  package.json
                                  node_modules

也遇到了这个问题。为我解决这个问题的方法是意识到 Windows 计算机上的文件路径太长。压缩后，我发现node_modules的内容是空的。我将要压缩的文件复制到更高级别的路径，例如 C:\User\ 并压缩指定的文件。希望这可以帮助！
