Question

我在将通知功能部署到firebase时遇到了困难。

我也使用了npm run clean但错误显示在其中 -

npm ERR! missing script: clean

index.js代码如下 -

'use strict'

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

exports.pushNotification = 

functions.database.ref('/Notifications/{user_id}/{notification_id}').onWrite(event => {

const user_id = event.params.user_id;
const notification = event.params.notification;
console.log('We have a notification to send to : ', user_id);

if(event.data.val()){

    return console.log('A Notification has been  deleted feom the database :', notification_id);

}

const deviceToken = admin.database().ref(`/Users/${user_id}/deviceToken).once('value');

return deviceToken.then(result => {

    const token_id = result.val();

    const payload = {
        notification: {
            title : "Friend Request",
            bosy : "You have received a new Friend Request",
            icon : "default"
        }
    };

    return admin.messaging().sendToDevice(/*Token ID*/, payload).then(response => {

        console.log('This was the notification Feature');

    });

});

}）;

命令提示符中的firebase部署错误是 -

C:\Users\NIHIR\Desktop\MilApp\notificationFunction>firebase deploy

=== Deploying to 'milapp2-55dfb'...

如何解决此错误？

在Windows 10中使用它。提前谢谢。

即使纠正了错误，我在部署firebase时再次收到错误 -

C:\Users\NIHIR\Desktop\MilApp\notificationFunction\functions\index.js

错误信息是：

19:61  error  Parsing error: Unterminated template

它指的是此行上的模板字符串未终止的事实：

const deviceToken = admin.database().ref(`/Users/${user_id}/deviceToken).once('value');

您错过了该参考字符串的结束反引号。它应该是这样的：

const deviceToken = admin.database().ref(`/Users/${user_id}/deviceToken`).once('value');

ELIFECYCLE错误。怎么解决？
