我在本地测试过，应用程序在5000端口使用快递

I tested locally, app is runnning at port 5000 using express

var express = require('express'),
    app = express();

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

// CORS (Cross-Origin Resource Sharing) headers to support Cross-site HTTP requests
app.all('*', function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    next();
});

// API Routes
// app.get('/blah', routeHandler);

app.set('port', process.env.PORT || 5000);

app.listen(app.get('port'), function () {
    console.log('Express server listening on port ' + app.get('port'));
});

推荐答案

我在这里看到一些问题

1）您需要一个procfile - https://devcenter.heroku.com/articles/getting-started-with-nodejs#define-a-procfile

1) You need a procfile - https://devcenter.heroku.com/articles/getting-started-with-nodejs#define-a-procfile

2）
您不要在package.json中指定引擎

2) You don't specify the engines in your package.json

"engines": {
  "node": "0.10.x"
},

参见here- https://discussion.heroku.com / t / the-official-node-js-buildpack-is-going-on-a-diet / 100

3） code> node_modules 目录为git。你应该能够使用 npm install （这就是你的 packages.json 文件）来下载包

3) You have comitted your node_modules directory to git. You should be able to download packages using npm install (that's what your packages.json file is for)

删除此目录，并将删除提交到git。
然后，创建一个 .gitignore 文件。将以下行添加到您的 .gitignore 文件中：

Delete this directory, and commit the delete to git. Then, create a .gitignore file. Add the following line to your .gitignore file:

node_modules

将此.gitignore文件提交到您的存储库。

commit this .gitignore file to your repository.

Git现在将忽略您的 node_modules _ 目录

Git will now ignore your node_modules_ directory
