我正在嘗試將 Elastic Search 集成到我的 Flutter 應用程式中。我正在嘗試部署一些功能，但似乎沒有任何效果。
這是我的 index.js 代碼：
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const { Client } = require('@elastic/elasticsearch')
admin.initializeApp(functions.config().firebase);
const env = functions.config();
const auth = {
username: env.elasticsearch.username,
password: env.elasticsearch.password,
};
const client = new Client({
node: env.elasticsearch.url,
auth: auth
})
exports.createPost = functions.firestore
.document('bookings/{BookingId}')
.onCreate( async (snap, context) => {
await client.index({
index: 'bookings',
type: '_doc',
id: snap.id,
body: snap.data()
})
});
exports.updatePost = functions.firestore
.document('bookings/{BookingId}')
.onUpdate( async (snap, context) => {
await client.update({
index: 'bookings',
type: '_doc',
id: context.params.BookingId,
body: snap.after.data()
})
});
exports.deletePost = functions.firestore
.document('bookings/{BookingId}')
.onDelete( snap => {
client.delete({
index: 'bookings',
type: '_doc',
id: snap.id,
})
});
這是packages.json：
{
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"lint": "eslint",
"serve": "firebase emulators:start --only functions",
"shell": "firebase functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"engines": {
"node": "16"
},
"main": "index.js",
"dependencies": {
"firebase-admin": "^10.0.2",
"firebase-functions": "^3.18.0"
},
"devDependencies": {
"eslint": "^8.9.0",
"eslint-config-google": "^0.14.0",
"firebase-functions-test": "^0.2.0"
},
"private": true
}
我使用 npm 安裝了 elasticsearch：
npm install @elastic/elasticsearch
每次部署時，我都會得到以下輸出：

該錯誤似乎表明找不到彈性搜索模塊，我不知道為什么。PS：我對 Javascript、Firebase Cloud Functions 和 Elastic Search 非常陌生。
uj5u.com熱心網友回復：
您的彈性搜索包未安裝成功。運行npm i @elastic/elasticsearch命令時，請確保您位于“ functions ”目錄中。如果問題仍然存在，您還可以從 npm 獲取最新版本的軟體包并將其手動添加到您的 package.json 中。您可以將其添加到您的依賴項中：
"@elastic/elasticsearch": "^8.2.0"
