Question

我正在尝试将一个函数部署到firebase，我在部署期间遇到错误

错误：功能未正确部署。

是否可以与异步功能链接？

实际行为 函数部署时出错，cli向我显示以下消息：

================ console log ================

================函数index.js文件================

const functions = require('firebase-functions');


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

   const { JWT } = require('google-auth-library/build/src/index');

   exports.sendContactEmailOAuth = functions.https.onRequest((req, res) => {
 const sender_msg = 'just a test'
 const email = 'contact@lechorodescharentes.org'

   const client = new JWT(
     functions.config().service_key.client_email,
     null,
     functions.config().service_key.private_key,
     ['https://www.googleapis.com/auth/cloud-platform', 'https://mail.google.com'],
   );
     await client.authorize();
      const url = `https://www.googleapis.com/dns/v1/projects/${functions.config().service_key.project_id}`;
   const res = await client.request({ url });
   console.log(res.data);

Answer 1

截至 2018年8月：

云功能现在支持节点8（8.11.1）。检出this blog post。

升级到节点8

按照this blog post中的建议，请按照以下步骤升级到节点8：

通过npm install --save firebase-functions@latest升级您的firebase-functions版本
通过npm update -g firebase-tools升级firebase-tools
将"engines": { "node": "8" }添加到您的/functions/package.json

Answer 2

如果您在最新版本（例如节点 12）上仍有问题，请使用 .eslintrc.js 文件中的 ecmaVersion 解析器选项。

这是一个示例：

module.exports = {
  root: true,
  env: {
    es6: true,
    node: true,
  },
  parserOptions: {
    ecmaVersion: 8,
  },
  extends: [
    "eslint:recommended",
    "google",
  ],
  rules: {
    quotes: ["error", "double"],
  },
};
