RangeError：在node_modules – > elasticsearch中超出最大调用堆栈大小
在尝试编写一个在Firebase函数上部署的函数时，我写了下面的代码：
'use strict'; const elasticsearch = require('elasticsearch'); const firebaseAdmin = require('firebase-admin'); const functions = require('firebase-functions'); const Promise = require('promise'); const config = { firebaseUrl: FIREBASE_URL, elasticSearchUrl: ELASTICSEARCH_URL }; // configure firebase const serviceAccount = require("./serviceAccountKey.json"); firebaseAdmin.initializeApp({ credential: firebaseAdmin.credential.cert(serviceAccount), databaseURL: config.firebaseUrl }); const database = firebaseAdmin.database(); const client = new elasticsearch.Client({ host: config.elasticSearchUrl }); exports.indexentry = functions.database.ref('/posts/{postid}/text').onWrite(event => { let data = event.data.val(); let post_id = event.params.postid; let indexData = { index: "firebase", type: "posts", id: post_id, body: data } return client.index(indexData).then(response => { console.log('Response: '); }); }); 我收到一个错误：
错误：分析函数触发器时发生错误。

在Github上的一条评论中，我发现了一个修正：它让我在我的代码中的任何地方添加这个：
var EventEmitter = require('events').EventEmitter; var Log = require('./node_modules/elasticsearch/src/lib/log'); Log.prototype.listenerCount = EventEmitter.prototype.listenerCount;
现在我得到一个错误：
Error: unknown error at respond (/user_code/node_modules/elasticsearch/src/lib/transport.js:234:15) at checkRespForFailure (/user_code/node_modules/elasticsearch/src/lib/transport.js:200:7) at HttpConnector.<anonymous> (/user_code/node_modules/elasticsearch/src/lib/connectors/http.js:155:7) at IncomingMessage.wrapper (/user_code/node_modules/elasticsearch/node_modules/lodash/index.js:3095:19) at emitNone (events.js:91:20) at IncomingMessage.emit (events.js:185:7) at endReadableNT (_stream_readable.js:974:12) at _combinedTickCallback (internal/process/next_tick.js:74:11) at process._tickDomainCallback (internal/process/next_tick.js:122:9) Error: unknown error at respond (/user_code/node_modules/elasticsearch/src/lib/transport.js:234:15) at checkRespForFailure (/user_code/node_modules/elasticsearch/src/lib/transport.js:200:7) at HttpConnector.<anonymous> (/user_code/node_modules/elasticsearch/src/lib/connectors/http.js:155:7) at IncomingMessage.wrapper (/user_code/node_modules/elasticsearch/node_modules/lodash/index.js:3095:19) at emitNone (events.js:91:20) at IncomingMessage.emit (events.js:185:7) at endReadableNT (_stream_readable.js:974:12) at _combinedTickCallback (internal/process/next_tick.js:74:11) at process._tickDomainCallback (internal/process/next_tick.js:122:9)
如何解决这个问题？
编辑
我按照第一个答案中的build议更新了elasticsearch。 现在我得到的错误：
Error: [mapper_parsing_exception] failed to parse at respond (/user_code/node_modules/elasticsearch/src/lib/transport.js:307:15) at checkRespForFailure (/user_code/node_modules/elasticsearch/src/lib/transport.js:266:7) at HttpConnector.<anonymous> (/user_code/node_modules/elasticsearch/src/lib/connectors/http.js:159:7) at IncomingMessage.bound (/user_code/node_modules/elasticsearch/node_modules/lodash/dist/lodash.js:729:21) at emitNone (events.js:91:20) at IncomingMessage.emit (events.js:185:7) at endReadableNT (_stream_readable.js:974:12) at _combinedTickCallback (internal/process/next_tick.js:74:11) at process._tickDomainCallback (internal/process/next_tick.js:122:9)
- 确保您使用的是最新版本的弹性search：
npm install elasticsearch。 在你的package.json文件中添加正确的依赖项，它应该是最近版本的弹性search，或者，使用commad，npm install elasticsearch@13.2.0或者其他任何版本。 - 您不需要实际覆盖
Log.prototype.listenerCount，Log.prototype.listenerCount已经在内部为您执行此操作（因此，调用堆栈recursion）。 所以，删除这一行：
Log.prototype.listenerCount = EventEmitter.prototype
此外，虽然这与您的问题无关…在要求path中包含./node_modules是多余的。 节点有一个内置的模块search机制，并为你做这个。
