【问题描述】：

我正在尝试复制 Dialogflow 博客的示例：https://blog.dialogflow.com/post/create-and-manage-entities-with-api/

代码如下：

    'use strict';

const admin=require('firebase-admin');


const dialogflow = require('dialogflow');

// Read in credentials from file. To get it, follow instructions here, but
// choose 'API Admin' instead of 'API Client':
// https://dialogflow.com/docs/reference/v2-auth-setup
const credentials = require('./test1drawio.json');

const entitiesClient = new dialogflow.EntityTypesClient(
 credentials: credentials,
);

const projectId = 'projectID';
const agentPath = entitiesClient.projectAgentPath(projectId);

const cityEntityType = 
    displayName: 'city',
    kind: 'KIND_MAP',
    entities: [
      value: 'New York', synonyms: ['New York', 'NYC'],
      value: 'Los Angeles', synonyms: ['Los Angeles', 'LA', 'L.A.'],
    ],
   ;

   const cityRequest = 
    parent: agentPath,
    entityType: cityEntityType,
   ;

   entitiesClient
      .createEntityType(cityRequest)
      .then((responses) => 
        console.log('Created new entity type:', JSON.stringify(responses[0]));

      const streetEntityType = 
        displayName: 'street',
        kind: 'KIND_MAP',
        entities: [
          value: 'Broadway', synonyms: ['Broadway'],
        ]
      ;

       const streetRequest = 
         parent: agentPath,
         entityType: streetEntityType,
       ;

       return entitiesClient.createEntityType(streetRequest);
     )

     .then((responses) => 
       console.log('Created new entity type:', JSON.stringify(responses[0]));
     )
     .catch((err) => 
        console.error('Error creating entity type:', err);
      );

如果我尝试执行它，将抛出答案标题中提到的错误。

我当然检查过 npm、Node 和其他包的版本，这是 package.json 文件：

    
  "name": "tesilaurea",
  "version": "1.0.0",
  "description": "Tesi di Laurea Dialogflow",
  "main": "index.js",
  "scripts": 
    "test": "echo \"Error: no test specified\" && exit 1"
  ,
  "author": "Lorenzo Neri",
  "license": "MIT",
  "keywords": [],
  "dependencies": 
    "dialogflow": "^0.10.3",
    "firebase-admin": "^8.3.0",
    "firebase-functions": "3.2.0",
    "grpc": "^1.20.2",
    "node": "12.8.0"
  ,
  "engines": 
    "node": "^8.13.0"
  

我重建、降级并再次尝试执行它，但没有成功。

【参考方案1】：

第 1 步。检查您的 NodeJS 版本，-node -v

第 2 步。 将您的节点升级到 LTS 或更高版本，要更新您可以使用 nvm 或 this

第 3 步。 更新后删除 package-lock.json 和 node_modules 文件夹，然后重新安装。
