无法将 node.js 应用程序部署到 heroku [英] Fail to deploy node.js application to heroku

问题描述

我正在尝试将一个简单的基于 node.js express 的应用程序部署到 heroku，这显然是非常基本的:https://devcenter.heroku.com/articles/nodejs

I am trying to deploy a simple node.js express-based application to heroku, something which is apparently very basic: https://devcenter.heroku.com/articles/nodejs

这是我的 package.json:

Here is my package.json:

{
  "name": "cours-lic3-blois",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app"
  },
  "dependencies": {
    "express": "*",
    "ejs": "*",
    "github-flavored-markdown": "*",
    "less-middleware": "*"
  },
  "engines": {
    "node": "0.8.8",
    "npm": "1.1.65"
  }
}

当我 git push heroku master 我得到以下跟踪:

When I git push heroku master I got the following trace:

 -----> Heroku receiving push
 -----> Node.js app detected
 -----> Resolving engine versions
        Using Node.js version: 0.8.8
        Using npm version: 1.1.65

  ! [remote rejected] master -> master (pre-receive hook declined)
 error: failed to push some refs to '[e-mail]:fast-everglades-2007.git'

我尝试调整 package.json 中的各种版本，但无济于事.我正在 Windows 上开发，这个 ENOENT 问题可能是由于某些文件模式问题造成的.

I tried to tweak various versions in my package.json but to no avail. I am developing on windows and it might be possible this ENOENT issue is due to some filemode issue.

推荐答案

我通过以下方式解决了这个问题:

I got this fixed by:

• 确保 Procfile 已提交到 git

• Making sure Procfile is committed into git

删除 node_modules/文件夹并将其提交到 git (git rm -r node_modules/)

Removing the node_modules/ folder and committing that into git (git rm -r node_modules/)

之后，我做了 git push heroku master 然后错误消失了.

Afterwards, I did the git push heroku master then the error disappeared.
