Question

按照圣诞节的12devs教程创建我的第一个Node.js应用程序（http://12devsofxmas.co.uk/post/2012-12-28-day-3-realtime-collaborative-drawing-with-nodejs）我现在正试图按照Rob Dodson的教程通过Heroku（http://robdodson.me/blog/2012/06/04/deploying-your-first-node-dot-js-and-socket-dot-io-app-to-heroku/）部署它

然而，在提交到github之后，当我尝试推送到Heroku时，我得到以下错误输出：

-----> Installing dependencies with npm

       Move it away, and try again.

To git@heroku.com:secure-dawn-2437.git

! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:secure-dawn-2437.git'

我的package.json文件如下：

{
    "name": "Draw",
    "version": "0.0.1",
    "private": true,
    "dependencies": {
      "express": "~2.x",
      "socket.io": "~0.9.x"
    },
    "engines": {
      "node": "0.6.x",
      "npm": "1.1.x"
    }
}

对不起 - 我对这种开发完全不熟悉，在学校里主要使用Java，但我很想学习。我认为这个问题在某种程度上是表达的，但是我不确定它是什么意思“将它移开，再试一次。”

Answer 1

您尝试部署的应用程序中是否有Procfile个文件？

如果没有，请查看Heroku网站上提供的文档：

https://devcenter.heroku.com/articles/nodejs#declare-process-types-with-procfile

修改

我强烈建议您首先部署一个非常简单的Node.js应用程序（如Hello World），这样您就可以追溯错误的来源。

Answer 2

尝试从.gitignore中删除bin和.bin，或者将node_modules添加到.gitignore。更多信息：Fail to deploy node.js application to heroku

Answer 3

我能够通过暂时禁用Heroku使用缓存来解决这个问题：

heroku config:set NODE_MODULES_CACHE=false

推送构建，然后重新打开缓存。

通过Heroku首次部署Node应用程序时出现问题
