部署 MERN 堆栈应用程序的问题

Question

我无法部署我的全栈应用程序。

就文件夹结构而言，我的存储库看起来完全一样：

以下是我的 package.json:https://github.com/bradtraversy/mern_shopping_list

你能试试这个吗-

即server.js文件内容：-

const express = require("express");
const path = require("path");
const app = express();
require("dotenv").config();
app.use(express.static(path.join(__dirname, "build")));

app.get("/", function(req, res) {
  res.sendFile(path.join(__dirname, "build", "index.html"));
});

app.get("/*", function(req, res) {
  res.sendFile(path.join(__dirname, "build", "index.html"));
});

app.listen(process.env.PORT || 3000);

这是我的脚本部分：-

  "scripts": {
    "start:production": "npm install && npm run build && npm run start:prod",
    "start:prod": "cross-env NODE_ENV=production node server",
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

在生产中启动命令：-

npm run start:production
