我正在尝试将功能部署到Firebase
$ npm install firebase-tools
$ login firebase
$ firebase init functions
然后$firebase deploy --only functions或$firebase deploy
package.json：
{
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"lint": "eslint .",
"serve": "firebase serve --only functions",
"shell": "firebase functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"dependencies": {
"firebase-admin": "~5.12.1",
"firebase-functions": "^1.0.3"
},
"devDependencies": {
"eslint": "^4.12.0",
"eslint-plugin-promise": "^3.6.0"
},
"private": true
}
firebase.json：
{
"functions": {
"predeploy": [
"npm --prefix \"%RESOURCE_DIR%\" run lint"
]
}
}
将$RESOURCE_DIR修改为%RESOURCE_DIR%，以避免：
错误：函数预部署错误：命令以非零终止 退出代码4294963238
我的功能index.js：
const functions = require('firebase-functions');
var admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
var wrotedata;
exports.Pushtrigger = functions.database.ref('/messages/{messageId}').onWrite((event) => {
wrotedata = event.data.val();
admin.database().ref('/pushtokens').orderByChild('uid').once('value').then((alltokens) => {
var rawtokens = alltokens.val();
var tokens = [];
this.processtokens(rawtokens).then((processedtokens) => {
for (var token in processedtokens) {
tokens.push(token.devtoken);
}
var payload = {
"notification": {
"title": "Notification title",
"body": "Notification body",
"sound": "default",
"click_action": "FCM_PLUGIN_ACTIVITY",
"icon": "fcm_push_icon"
},
"data": {
"message": "value1",
"sendername": "value2"
}
}
return admin.messaging().sendToDevice(tokens, payload).then((response) => {
console.log('Push notifications');
}).catch((err) => {
console.log(err);
})
})
})
})
function processtokens(rawtokens) {
var promise = new Promise((resolve, reject) => {
var processedtokens = []
for (token in rawtokens) {
processedtokens.push(rawtokens[token]);
}
resolve(processdatatokens);
})
return promise;
}
我尝试过：
npm install firebase-admin@latest firebase-functions@latest
npm install -g git://github.com/firebase/firebase-tools#master
但是我得到了：

编辑：
如果以firebase.json格式从\"%RESOURCE_DIR%\"到"%RESOURCE_DIR%"进行编辑，则
错误：加载firebase.json时出错：意外令牌'％' “ npm --prefix”％RESOURCE_DIR％“运行皮棉”
如果我从firebase.json中删除行并在终端中运行npm --prefix "%RESOURCE_DIR%" run lint：

答案 0 :(得分：1)
您的部署前标志npm --prefix \"%RESOURCE_DIR%\" run lint引起了您的问题。
如果您在终端中运行npm --prefix "%RESOURCE_DIR%" run lint，它是否可以正确运行且没有错误？
如果您从firebase.json中删除该行，则该行应该没有问题。

检查收到的错误消息，它会为您找到答案。您的代码linter失败了，您需要先修复这些错误，然后才能进行部署。

我快速浏览了您的代码，并且我认为我已经清理了它。另外，您无需承诺processtokens，它是一个同步功能。
const functions = require('firebase-functions');
var admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
var wrotedata;
exports.Pushtrigger = functions.database.ref('/messages/{messageId}').onWrite((event) => {
wrotedata = event.data.val();
return admin.database().ref('/pushtokens')
.orderByChild('uid')
.once('value')
.then((alltokens) => {
var rawtokens = alltokens.val();
var tokens = [];
var processedtokens = this.processtokens(rawtokens);
for (var token in processedtokens) {
tokens.push(token.devtoken);
}
var payload = {
