Javascript 希罗库；React部署成功，但出现应用程序错误

我的构建和应用程序部署成功，但我的应用程序仍无法部署。我尝试过更改服务器端口、更新依赖项、重新部署、重建和重新提交。我不知道该怎么办

我已经尝试了我能想到的一切，任何帮助都将不胜感激我的服务器有问题吗？还是别的什么？救救我

我的服务器文件：

import express from 'express';
import path from 'path';
import open from 'open';

/* eslint-disable no-console */

const PORT = 8080;
const app = express();

app.use(express.static('dist'));

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

app.listen(process.env.PORT || 5000);

我的Heroku日志：

根据您的项目，并参考本手册，了解正确的设置

看起来您的启动功能不是在npm start上运行的，因为它不会启动dist服务器。 由于heroku在默认情况下尝试运行npm start，所以它会像在开发环境中一样启动它

我会将package.json中的“脚本”更改为

"scripts": {
    "prestart": "babel-node ./tools/startMessage.js",
    "start-dev": "npm-run-all --parallel open:src lint:watch test:watch",
    "start": "node tools/distServer.js",
    "open:src": "babel-node tools/srcServer.js",
    "lint": "node_modules/.bin/esw webpack.config.* src tools",
    "lint:watch": "npm run lint -- --watch",
    "test": "mocha --reporter spec tools/testSetup.js \"src/**/*.test.js\"",
    "test:watch": "npm run test -- --watch",
    "clean-dist": "npm run remove-dist && mkdir dist",
    "remove-dist": "node_modules/.bin/rimraf ./dist",
    "build:html": "babel-node tools/buildHtml.js",
    "prebuild": "npm-run-all clean-dist test lint build:html",
    "build": "babel-node tools/build.js",
    "postbuild": "babel-node tools/distServer.js"
},

您还必须删除import语句才能在heroku服务器上工作，因此将distServer.js更改为

const express = require('express');
const path = require('path');
const open = require('open');

/* eslint-disable no-console */

const PORT = 8080;
const app = express();

app.use(express.static('dist'));

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

app.listen(process.env.PORT || 5000);

---

编辑。使用这些更改，我可以部署到测试heroku服务器，祝您好运。看起来是个有趣的项目
