如何在 DialogFlow 的 Package.json 文件中添加新的依赖项？

Question

I just started creating a chatbot and I want it to be multilingual. So, I am using i18n module for the same. I added it's dependency in the package.json but now it is showing an error:

The deployment of your Cloud Function failed:
Build failed: Build error details not available

This is my package.json file:

  "name": "dialogflowFirebaseFulfillment",

And this is my index.js file:

// See https://github.com/dialogflow/dialogflow-fulfillment-nodejs
// for Dialogflow fulfillment library docs, samples, and to report issues
'use strict';

const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const i18n= require('i18n');

process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

i18n.configure({
    locales : ['en-IN','hi-IN-1'],
    directory : '',
    defaultLocale : 'en-IN'
});

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
  const agent = new WebhookClient({ request, response });
  console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
  console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

  function welcome(agent) {
    agent.add(`Welcome to my agent!`);
  }

  function fallback(agent) {
    agent.add(`I didn't understand`);
    agent.add(`I'm sorry, can you try again?`);
  }

  function About(agent){
    agent.add(`We are a company!`);
  }

  // // Uncomment and edit to make your own intent handler
  // // uncomment `intentMap.set('your intent name here', yourFunctionHandler);`
  // // below to get this function to be run when a Dialogflow intent is matched
  // function yourFunctionHandler(agent) {
  //   agent.add(`This message is from Dialogflow's Cloud Functions for Firebase editor!`);
  //   agent.add(new Card({
  //       title: `Title: this is a card title`,
  //       imageUrl: 'https://developers.google.com/actions/images/badges/XPM_BADGING_GoogleAssistant_VER.png',
  //       text: `This is the body text of a card.  You can even use line\n  breaks and emoji! 💁`,
  //       buttonText: 'This is a button',
  //       buttonUrl: 'https://assistant.google.com/'
  //     })
  //   );
  //   agent.add(new Suggestion(`Quick Reply`));
  //   agent.add(new Suggestion(`Suggestion`));
  //   agent.setContext({ name: 'weather', lifespan: 2, parameters: { city: 'Rome' }});
  // }

  // // Uncomment and edit to make your own Google Assistant intent handler
  // // uncomment `intentMap.set('your intent name here', googleAssistantHandler);`
  // // below to get this function to be run when a Dialogflow intent is matched
  // function googleAssistantHandler(agent) {
  //   let conv = agent.conv(); // Get Actions on Google library conv instance
  //   conv.ask('Hello from the Actions on Google client library!') // Use Actions on Google library
  //   agent.add(conv); // Add Actions on Google library responses to your agent's response
  // }
  // // See https://github.com/dialogflow/fulfillment-actions-library-nodejs
  // // for a complete Dialogflow fulfillment library Actions on Google client library v2 integration sample

  // Run the proper function handler based on the matched Dialogflow intent name
  let intentMap = new Map();
  intentMap.set('Default Welcome Intent', welcome);
  intentMap.set('Default Fallback Intent', fallback);
   intentMap.set('About the company', About);
  // intentMap.set('your intent name here', googleAssistantHandler);
  agent.handleRequest(intentMap);
});

Most probably, the error is in the JSON file. Can anybody please help me with this?

Answer 1

You appear to be using multiple objects in a list inside your package.json file, I'm not sure if this is how package.json files are meant to work.

[{

},{

}]

Could you try compress all your sections down into a single object, eg.

{

}

ie, move dependencies into a single section etc.

Answer 2

You can add the npm package: i18n to your dependencies object in package.json like this:

"dependencies": {
  "actions-on-google": "^2.2.0",
  "firebase-admin": "^5.13.1",
  "firebase-functions": "^2.0.2",
  "dialogflow": "^0.6.0",
  "dialogflow-fulfillment": "^0.5.0",
  "i18n" : "^0.8.4"
}
