Question

我已经尝试将Angular 7应用程序部署到Heroku几天了，并且在构建成功后一直遇到应用程序错误。我意识到我的整个/ dist文件夹都位于.gitignore中，因此我将其删除了，但仍然遇到应用程序错误。我检查了heroku日志（“启动脚本失败”），这是我跳出来的错误，不确定如何继续：

TypeError：对象原型只能是一个Object或为null： dist / hockey-app在Function.create（）在 Function.serveStatic [静态] （/app/node_modules/serve->static/index.js:48:21）。（/app/server.js:7:23）

这是node_modules / serve-> static / index.js的样子：在指示的行：

// copy options object
  var opts = Object.create(options || null)

编辑：Server.js

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

const app = express();

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

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

const port = process.env.PORT || 3000;
app.set('port', port);

const server = http.createServer(app);
server.listen(port, () => console.log('running'));

和我的package.json

现在查看您的server.js文件... express.static()方法不应该接受您传递的内容。

尝试使用path.join(__dirname, "path/to/index")，然后将完整路径传递给静态方法。
