Question

所以我搜索了几个小时，似乎找不到我要的答案。

我正在尝试将一个简单的React / Express / Node应用程序部署到Heroku，并且似乎无法使其正常工作。

这是我的文件：

server.js：

const express = require('express');
const path = require('path');
const app = express();
const port = process.env.PORT || 5000;

app.listen(port, () => console.log(`Listening on port ${port}`));

app.use(express.static(path.join(__dirname, '/client/dist')));

app.get('/', (req, res) => {
  res.send('working');
});

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

package.json脚本（服务器端）

  "scripts": {
    "client": "cd client && yarn start",
    "server": "nodemon server.js",
    "dev": "concurrently \"yarn server\" \"yarn client\"",
    "start": "node server.js",
    "heroku-postbuild": "cd client && yarn && yarn build"
  }

package.json脚本（客户端）：

  "scripts": {
    "start": "webpack-dev-server --mode development",
    "build": "webpack --mode production"
  },
  "proxy": "http://localhost:5000"
}

这是我从Heroku中得到的错误：

任何帮助将不胜感激。现在后端没有任何反应，我只是想显示我的React应用。

部署React / Node应用后，从Heroku不断收到错误“ App崩溃”方法=“ GET path =” /“
