PS C:\Users\USER\Documents\aaa-PROJECTS\Main-accounting-app>

这是我的procfile

web: node app.js

这是我的appjs

var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
const mongoose = require('mongoose');
const cors = require('cors');
const bodyParser = require('body-parser');


var indexRouter = require('./api/routes/index');
var usersRouter = require('./api/routes/users');

mongoose.connect('mongodb://xxx:xxx.mlab.com:39921/demobusinesshub',{
    // mongodb://localhost:27017/testbusinesshub
    // mongodb://xxx:xxx.mlab.com:39921/demobusinesshub
}).then(c => console.log('connected to db'))
.catch(c => console.log('connection to db error'))

var app = express();
app.use(cors());

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));

app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

// bodyparser

app.use(bodyParser.json());

app.use('/', indexRouter);
app.use('/users', usersRouter);

const port = process.env.PORT || 3000;
const host = '0.0.0.0';

app.listen(port, host, ()=>{
    console.log('Server started on port '+ port);
});
module.exports = app;

这是我的包json

以及我的角度服务的身份验证文件中

return this.http.post('' + this.domain + 'users/register', newUser, {headers: headers}).pipe(map(res => res.json()));

生产中的位置this.domain =''//（一个空字符串）

所以我不明白问题出在哪里，我从字面上搜索了网络，并被告知要检查端口等，我已经做了所有这些事情。在这个阶段我真的很困惑，我不知道该做什么。我也已经在我的角度终端中进行了构建，并将其捆绑到我的快速应用程序的公用文件夹中。使用heroku本地作品运行此文件，不会出现任何错误。也可以在我的普通本地服务器上运行它

Answer 1

这个问题的答案：https://pastebin.com/3bqTbHsv在stackoverflow上，问题是您在Windows机器上安装了模块 bcrypt ，而heroku机器是linux，并且将该模块推到了heroku机器上， bcrypt 依赖项将不起作用。

要修复此问题，请删除heroku机器上的 node_modules 文件夹，然后将.gitignore文件添加到您的项目中，并在文件中添加以下行：

node_modules

然后运行： git add。并推送到heroku master。因此heroku机器会自动安装依赖项，包括Linux的 bcrypt 。

部署到heroku时，我的应用程序不断崩溃。我收到这个担心的应用程序错误主屏幕
