Angular heroku local工作正常，但不在线（爱奥尼亚&；firebase后端）

我正在将带有firebase后端的ionic（v.4）部署到Heroku，但该应用程序只能在本地运行，当我运行git push Heroku master构建应用程序时，它不起作用

heroku日志显示：

这就是构建过程：

Server.js:

var express = require("express");
var app = express();
var morgan = require("morgan");
var bodyParser = require("body-parser");
var cors = require("cors");

app.use(morgan("dev"));
app.use(bodyParser.urlencoded({ extended: "true" }));
app.use(bodyParser.json());
app.use(cors());

app.use(function (req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Methods", "DELETE, PUT");
  res.header(
    "Access-Control-Allow-Headers",
    "Origin, X-Requested-With, Content-Type, Accept"
  );
  next();
});

app.use(express.static("www"));
app.set("port", process.env.PORT || 5000);
app.listen(app.get("port"), function () {
  console.log("Express server listening on port " + app.get("port"));
});

package.json:我已经将typescript和app script从devdependency移到了devdependence

你能提供你的package.json文件吗？我已经用package.json编辑了我的问题帖子。请检查。不确定为什么会发生这种情况，但在构建时，您的应用程序缺少angular/cli依赖项，如日志所示。希望这有助于进一步调查这个问题。我曾尝试将angular/cli和angular commpiler/cli移动到依赖项，但对依赖项无效。它给出了新的错误：发生了未处理的异常：找不到模块'@angular devkit/build angular/package.json'尝试将所有angular dev依赖项移动到依赖项中。它们是构建应用程序所必需的，heroku似乎没有安装开发依赖项
