Firebase 将 Sapper 应用程序部署为云功能失败

Question

问题

我正在构建 Sapper SSR 应用，该应用会根据 Firebase 实时数据库所需的数据从 Firebase 存储中加载内容。我的应用部署在 Firebase 云功能上。但是我上次部署时遇到了这个错误，自从上次部署以来，我实现了从实时数据库和其他次要功能中加载一些数据，所以我不知道是什么导致了这个错误。

部署命令：

/usr/bin/node /usr/local/lib/node_modules/npm/bin/npm-cli.js run deploy:functions --scripts-prepend-node-path=auto

> violette-website@0.0.1 deploy:functions /home/hejtmus/Documents/Websites/Violette/sapper/Violette/functions
> firebase deploy --only functions:ssr

Functions deploy had errors with the following functions:

To try redeploying those functions, run:
    firebase deploy --only "functions:ssr"


To continue deploying other features (such as database), run:
    firebase deploy --except functions

Firebase 日志：

错误：函数终止。建议的操作：检查日志以了解终止原因。函数无法初始化。

我尝试了什么

我试过了：

• 在开发模式下运行应用程序，完美运行

• 将应用程序构建为 js 函数，完美运行

• 通过firebase serve 服务应用程序，完美运行

• 使用firebase deploy 或firebase deploy --only functions 部署应用程序，它们都不起作用，抛出指定错误

• 检查代码是否有错误和配置错误，什么也没发现

我尝试用这篇文章中的知识解决这个问题，我按照这个教程一步一步，但我仍然得到同样的错误：

https://blog.logrocket.com/build-an-ssr-web-app-with-firebase-functions-hosting-and-svelte-sapper/

我还尝试删除我添加的代码并部署应用程序而不从 firebase 实时数据库加载数据，但它没有帮助。

代码：

index.js（云函数）：

const functions = require('firebase-functions');
const { sapperServer } = require('./__sapper__/build/server/server');

exports.ssr = functions.https.onRequest(sapperServer);

server.js:

import sirv from 'sirv';
import express from 'express';
import compression from 'compression';
import * as sapper from '@sapper/server';

const { PORT, NODE_ENV } = process.env;
const dev = NODE_ENV === 'development';

const sapperServer = express()
    .use(
        compression({ threshold: 0 }),
        sirv(`static`, { dev }),
        sapper.middleware()
    )
if(dev){
    sapperServer.listen(PORT, err => {
        if (err) console.log('error', err);
    });
}

export { sapperServer }

如果需要，我会提供更多信息。

出了什么问题

问题是，我在浏览器中使用了 firebase，Svelte 是编译器，它在 Node.js 环境中运行，它必须由代码捆绑器捆绑（我使用汇总）。为了能够在节点中运行 firebase，只需在汇总配置中指定 mainFields。

resolve({
    browser: true,
    dedupe: ['svelte'],
    mainFields: ['main']
}),

我只在客户端使用firebase，所以在我的情况下不需要在服务器中指定mainFields参数。
