尝试部署 Firebase 功能时出现 ESLint 错误

Question

我尝试部署一个 firebase 功能，但由于 ESLint 的一些问题，它一直失败。我也试过用谷歌搜索答案，但我看到的一切对我来说都是希腊语。

我也偶然发现了 这个 和 这个 答案，但似乎它们不适用于我的场景。

我的功能

// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
// exports.helloWorld = functions.https.onRequest((request, response) => {
//  response.send("Hello from Firebase!");
// });

//import firebase functions modules
const functions = require("firebase-functions");
//import admin module
const admin = require("firebase-admin");
admin.initializeApp(functions.config().firebase);

// Listens for new messages added to messages/:pushId
exports.pushNotification = functions.database.ref("/Message").onWrite( event => {
    //  Grab the current value of what was written to the Realtime Database.
    var valueObject = event.data.val();
    // Log the event
    console.log("Push notification event triggered for " + valueObject.title);

    //if(valueObject.title != null) {
      //valueObject.photoUrl= "Sent you a photo!";
   // }

  // Create a notification
    const payload = {
        data: {
            body:valueObject.body,
            imgUrl: valueObject.imgUrl,
            postUrl: valueObject.postUrl,
            title: valueObject.title
        },
    };

  //Create an options object that contains the time to live for the notification and the priority
    const options = {
        priority: "high",
        timeToLive: 60 * 60 * 24
    };

    return admin.messaging().sendToTopic("Posts", payload, options);
});

Answer 1

我可以想象您的项目进入这种状态的唯一方法是，如果您在项目创建时拒绝允许 npm 安装依赖项。所以当你问这个问题时：

?你想现在用 npm 安装依赖项吗？

您可能已经回答“不”。这将阻止安装 eslint 包，并且您会看到该错误。

否则，您可能已经以某种方式删除了 node_modules 下的 eslint 安装包。您可以从 functions 文件夹运行 npm install 以重新创建 node_modules 下所需的所有内容。

Answer 2

容易修复。在你的 package.json 里面改变

> "lint": "eslint ."

到

"lint": "eslint",
