Javascript Firestore云功能在本地不工作

我创建了一个测试项目，并根据文档配置了所有内容，但当我运行该项目时，它并没有按照预期工作，在编写此问题之前，我在谷歌上搜索了一些重复的问题，但每个问题的场景都不一样，所以我假设这不是一个重复的问题

以下是我的终端命令和输出：

functions ➤ npm run serve                                                                                         

> functions@ serve /Users/codecrash/Developments/crm-firestore/functions
> firebase serve --only functions

✔  functions: Using node@8 from host.
✔  functions: Emulator started at http://localhost:5000
i  functions: Watching "/Users/codecrash/Developments/crm-firestore/functions" for Cloud Functions...
i  Your code has been provided a "firebase-admin" instance.
i  functions: HTTP trigger initialized at http://localhost:5000/demo-crm/us-central1/helloWorld

Ignoring trigger "onUpdate" because the Cloud Firestore emulator is not running.
i  functions: Beginning execution of "helloWorld"
i  Your code has been provided a "firebase-admin" instance.
i  functions: Finished "helloWorld" in ~1s

我不确定，怎么了。helloWorld工作正常，但onUpdate和onWrite没有工作

我还尝试运行以下命令

functions ➤ firebase emulators:start

i  functions: HTTP trigger initialized at http://localhost:5001/demo-crm/us-central1/helloWorld

✔  functions: Trigger "onWrite" has been acknowledged by the Cloud Firestore emulator.
i  functions: Setting up Cloud Firestore trigger "onUpdate"
✔  functions: Trigger "onUpdate" has been acknowledged by the Cloud Firestore emulator.
i  functions: Beginning execution of "helloWorld"
i  Your code has been provided a "firebase-admin" instance.
i  functions: Finished "helloWorld" in ~1s

但使用onUpdate或onWrite触发器仍然不走运。 不知道我做错了什么

以下是我的代码库：

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp({});

exports.helloWorld = functions.https.onRequest((request, response) => {
    response.send("Hello from Firebase!");
});

exports.onWrite = functions.firestore.document('users/{userId}').onWrite((change, context) => {

    const document = change.after.exists ? change.after.data() : null;
    const oldDocument = change.before.data();
    // perform desired operations ...
    console.log('local: onWrite change:', change);
    console.log('local: onWrite context:', context);
    console.log('local: onWrite document:', document);
    console.log('local: onWrite oldDocument:', oldDocument);
    return Promise.resolve();
});


exports.onUpdate = functions.firestore.document('users/{userId}').onUpdate((change, context) => {
    const document = change.after.exists ? change.after.data() : null;
    const oldDocument = change.before.data();

    // perform desired operations ...
    console.log('local: onUpdate change:', change);
    console.log('local: onUpdate context:', context);
    console.log('local: onUpdate document:', document);
    console.log('local: onUpdate oldDocument:', oldDocument);
    return new Promise().then(() => {
        return Promise.resolve();
    }).catch((error) => {
        return Promise.reject('error:code_crash');
    });
});

我在env变量中添加了键：

GOOGLE_APPLICATION_CREDENTIALS="/Users/codecrash/Developments/crm-firestore/functions/certificate.json"
FIREBASE_CONFIG="/Users/codecrash/Developments/crm-firestore/functions/certificate.json"

注意：当我在云功能上部署它时，它工作正常。

谢谢。

我不知道为什么文档中没有明确提到这一点，但很明显，客户端sdk需要了解模拟器。存在将客户端sdk指向本地仿真器实例的方法。下面是我在初始化firebase应用程序后如何在项目中设置它。希望有帮助

firebase.initializeApp（配置）；
if（process.env.NODE_env===‘development’）{
firebase.functions（）.useFunctionsEmulator（'http://localhost:5001');
}

更新

当这个问题被问到（并得到回答）时，firebase本地模拟器正在研制中。因此，文件不充分。Firebase现在支持几乎所有被称为的服务（而不是存储），并且有很好的文档。请查看。

您使用的Firebase CLI版本是什么？运行

firebase--version

@DougStevenson它是6.10.0，您找到解决方案了吗？我在这里运行相同的问题相同，请在这里帮助firebase 7.1.0版的相同问题。它也不起作用。让我试试这个解决方案。谢谢：）Hi@ron4ex，我收到错误firebase.functions（）不是函数，在我的例子中firebase是admin（npm firebase admin module），知道吗？我不知道你想实现什么。上面的代码是从客户端sdk本地触发云函数。我怀疑不支持手动触发客户端应用程序：当我添加此应用程序时，

if（process.env.NODE_env==='development'）{firebase.functions（）.useFunctionsEmulator（'development'）http://localhost:5001“）；}

，网页包抛出错误

default.a.functions不是函数

。知道怎么修吗？
