Firebase初始化错误。 （节点：82729）UnhandledPromiseRejectionWarning

Question

当我在我的React应用中启动Firebase时， 经过一些firebase询问后，出现主题错误。

下面将详细介绍。

What language would you like to use to write Cloud Functions? (Use arrow keys)

当我用来创建一些React应用时，我没有出现这样的错误。但是，我今天遇到了这个错误。我想我的node.js上会出现这个错误。但是我不知道如何修复node.js。

我是node.js和firebase的初学者。 我该如何解决该错误？

我试图修复一些我在Internet上找到的解决方案。正在关注

我确实从v10.12.3重新安装了node.js v12.18.3。此外，我还在Mac上重新安装了Firebase-tools。我尝试在Firebase初始化之前在我的React应用上重新安装Firebase。

此外，我忽略了此错误，然后完成了Firebase的初始化。但是当我进行firebase部署时，我无法做到这一点。相反，我在命令行中遇到了此错误。

Error: HTTP Error: 404, Method not found.

现在，我无法解决此错误。 如果您有任何想法，请帮助我。 谢谢您的阅读！

06/09/2020添加了我的firebase.json并做出了响应package.json。 这是firebase.json

{
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint"
    ]
  },
  "hosting": {
    "public": "build",
    "ignore": [
      "firebase.json",
      "**/.*",

    ],
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  }
}

这是package.json

{
  "name": "react-bot",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",

    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

已经安装的软件包。

firebase-tools@8.10.0

firebase@7.19.1

node.js v12.18.3

macOS10.15.6

，如果我做了firebase deploy，则会收到此错误。

我尝试用％RESOURCE_DIR％替换“ $ RESOURCE_DIR”。我遇到了另一个错误。

Answer 1

首先更新firebase-tools：

Function<Integer, Consumer<Integer>> f3 = n -> x -> {
    System.out.println(x * factorial.apply(n));
};

Consumer<Integer> c = f3.apply(5);

c.accept(1); // 120
c.accept(2); // 240
c.accept(3); // 360
c.accept(4); // 480

看到您的屏幕截图后，在部署该功能时我能够看到错误。

尝试在npm install -g firebase-tools 文件中将$ RESOURCE_DIR替换为％RESOURCE_DIR％。

多平台解决方案

Linux

firebase.json

PowerShell

"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint"
]

Cmd.exe

"predeploy": [
"npm --prefix $Env:RESOURCE_DIR run lint"
]
