您好，我在使用 javascript 在 firebase 中部署函数时遇到错误

Question

.eslintrx.js

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

index.js

let functions = require('firebase-functions');
let admin = require('firebase-admin');

admin.initializeApp();

exports.onConversationCreated;
onConversationCreated = functions.firestore.document("Conversations/chatID").onCreate((snapshot, context) => {
    let data = snapshot.data();
    let chatID = context.params.chatID;
    if (data) {
      let members = data.members;
      for (let index = 0; index < members.length; index++) {
        let currentUserID = members[index];
        let remainingUserIDs = members.filter((u= string) => u !== currentUserID);
        remainingUserIDs.forEach(async (m= string) => {
          try {
            let _doc = await admin.firestore().collection("Users").doc(m).get();
            let userData = _doc.data();
            if (userData) {
              return admin.firestore().collection("Users").doc(currentUserID).collection("Conversations").doc(m).create({
                "chatId": chatID,
                "image": userData.image,
                "name": userData.name,
                "unseenCount": 0,
              });
            }
            return null;
          } catch (e) {
            return null;
          }
        });
      }
    } return null;
  });

我得到的错误：

Having trouble? Try firebase [command] --help

Answer 1

我的情况和你一样，所以我把我的快速解决方案留给你。 预部署时“运行 lint”会导致错误，Unexpected token => ，但众所周知，这不是错误。

解决方案

1. 清理掉.eslintrx.js后，它就可以工作了。

2. 删除firebase.json 文件中的一些行。

   在firebase.json 文件中，

    ...
      "functions": {
        "predeploy": [
          "npm --prefix \"$RESOURCE_DIR\" run lint"  << DELETE THIS LINE
        ]
      }

• 如果您使用 Windows，\"$RESOURCE_DIR\" 应该是 \"%RESOURCE_DIR%\"

1. ⭐⭐ 在index.js文件顶部添加/* eslint-disable */

   （我选择了这个）

2. 如果你想持久化 eslint 预部署，请使用 eslint 配置文件。例如，

  env: {
    es6: true, -> es2017 or higher?? will it work??
    node: true,
  },

见https://eslint.org/docs/user-guide/configuring/language-options#specifying-environments

5. 在 github 线程中查找更多信息： https://github.com/eslint/eslint/issues/8126
