node.js - dynamoose.setDocumentClient 不是函数

Question

我正在使用 dynamoose@2.8.5 并尝试使用 Dynamoose 设置 DAX。这是我的代码

const AmazonDaxClient = require('amazon-dax-client');
  var AWS = require('aws-sdk');
  const config = require('config');
  const dynamoose = require('dynamoose');
  AWS.config.update({
    region: config.region,
    accessKeyId: config.aws.key,
    secretAccessKey: config.aws.secret,
  });
  const dax = new AmazonDaxClient({ endpoints: ['daxEndPoint'] });
  const daxClient = new AWS.DynamoDB.DocumentClient({ service: dax });
  await dynamoose.setDocumentClient(daxClient);

但出乎意料的是，它向我抛出了错误dynamoose.setDocumentClient is not a function

任何帮助都会非常感激
