Question

我正在尝试将Reactjs应用程序推送到Heroku。

这是我的package.json文件：

{
  "name": "redux-simple-starter",
  "version": "1.0.0",
  "description": "Simple starter package for Redux with React and Babel support",
  "main": "index.js",
  "repository": "git@github.com:ldco2016/efUtube.git",
  "scripts": {
    "dev": "node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js",
    "postinstall": "webpack -p",
    "start": "node server.js",
    "test": "mocha --compilers js:babel-core/register --require ./test/test_helper.js --recursive ./test",
    "test:watch": "npm run test -- --watch"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.2.1",
    "babel-loader": "^6.2.0",
    "babel-preset-es2015": "^6.1.18",
    "babel-preset-react": "^6.1.18",
    "chai": "^3.5.0",
    "chai-jquery": "^2.0.0",
    "jquery": "3.0.0",
    "jsdom": "^8.1.0",
    "mocha": "^2.4.5",
    "react-addons-test-utils": "^0.14.7",
    "webpack": "^1.12.9",
    "webpack-dev-server": "^1.14.0"
  },
  "dependencies": {
    "babel-preset-stage-1": "^6.1.18",
    "lodash": "^3.10.1",
    "node": "9.4.0",
    "react": "^0.14.3",
    "react-dom": "^0.14.3",
    "react-redux": "^4.0.0",
    "react-router": "^2.0.1",
    "redux": "^3.0.4",
    "youtube-api-search": "0.0.5"
  }
}

我进行了一次：

npm install -g webpack以及webpack -p

我创建了一个server.js文件并使用以下代码完成了它：

const express = require('express');
const path = require('path');
const port = process.env.PORT || 8080;
const app = express();

app.use(express.static(__dirname));

app.get('*', (req, res) => {
  res.sendFile(path.resolve(__dirname, 'index.html'))
});

app.listen(port);
console.log('Server started');

当我在命令行中运行node server.js但在提交和推送更改并运行时，它在本地工作：

git push heroku master我反复收到此错误：

使用此命令node -v检查节点版本，使用此命令npm -v检查npm版本，然后在package.json中指定节点和npm版本，如下所示：

"engines": { "node": "8.1.x", "npm": "5.0.x" },

确保在依赖项列表和devDependencies之前指定它。
