firebase - Firestore/Firebase 模拟器未运行

问题描述

我正在尝试使用此处列出的指南在本地测试我的功能 https://firebase.google.com/docs/functions/local-emulator

我已经安装了最新的 firebase-tools 使用

npm install -g firebase-tools

在我的package.json我确认正在运行

"firebase-admin": "^7.3.0",
"firebase-functions": "^2.3.1",

当我尝试使用

firebase emulators:start

它给了我以下输出。我究竟做错了什么？ 

Starting emulators: ["functions"]
⚠  Your requested "node" version "8" doesn't match your global version "11"
✔  functions: Emulator started at http://localhost:5001

解决方案

我遇到了同样的问题，对我来说有一些问题

  1. 确保通过运行安装模拟器 firebase setup:emulators:firestore

我的第二个问题是我的初始 firebase 配置已将配置文件安装到我的主文件夹而不是[here]描述的项目文件夹中， 这意味着我的项目缺少 firestore.rules 和 firestore.indexes.json 以及一些配置设置.

运行firebase init以生成这些文件

一旦我解决了这两件事，它就对我有用。我希望这有帮助。

作为参考，我的 firebase.json 看起来像这样

{
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint",
      "npm --prefix \"$RESOURCE_DIR\" run build"
    ]
  },
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "hosting": {
    "public": "dist",
    "ignore": ["firebase.json", "**/.*", "**/node_modules/**"],
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  },
  "emulators": {
    "firestore": {
      "port": "5002"
    }
  }
}
