Heroku使用Node.js部署失败

4

我正在尝试将本地文件推送到Heroku，但出现以下错误。我的代码在Github中。请有经验的人帮我解决问题。谢谢。

$ heroku buildpacks:set heroku/nodejs
Buildpack set. Next release on haz will use heroku/nodejs.
Run git push heroku master to create a new release using this buildpack.
$ git push heroku master

关于package.json

{
  "name": "haz",
  "version": "1.0.0",
  "description": "Hazzir: An Ionic project",
  "private": "true",
  "dependencies": {
    "express": "^4.13.3"    
  },
  "main": "serve.js",
  "scripts": {

    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "engines": {
      "node": "4.1.2",
      "npm": "3.4.0"
    },

}

我在本地进行了测试，使用express将应用程序运行在5000端口上。

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'));
});

尝试：git add -f package.json 这对我有效。

git init 然后重新添加 heroku 远程连接即可

heroku git:remote -a yourappname

我看到这里有几个问题：

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

2）你没有在 package.json 中指定引擎。

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

请看这里- https://discussion.heroku.com/t/the-official-node-js-buildpack-is-going-on-a-diet/100 3) 您已经将node_modules目录提交到git。您应该能够使用npm install下载软件包（这是您的packages.json文件的作用）。

删除此目录，并将其删除提交到git。然后，创建一个.gitignore文件。在.gitignore文件中添加以下行：

node_modules

将此 .gitignore 文件提交到您的代码库中。

Git 现在将会忽略您的 node_modules_ 目录。
