无法在Heroku中部署NodeJS App [英] Not able to deploy NodeJS App in Heroku

问题描述

我使用JetBrain Webstrom创建了一个NodeJS应用，现在我想将其部署到heroku.

I created a NodeJS app using JetBrain Webstrom and now i would like to deploy it to heroku.

此图片包含我的应用目录

我应该删除node_modules来部署应用程序吗?还是应该在package.json下添加任何引擎"部分?我应该怎么做才能将我的应用正确部署在heroku中.

Should I remove node_modules to deploy the app ? or should i add any "engine" section under package.json ? What should I do to get my app deployed properly in heroku.

我的应用的package.json:

My app's package.json:

{
  "name": "form",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "body-parser": "~1.15.2",
    "cookie-parser": "~1.4.3",
    "debug": "~2.2.0",
    "ejs": "~2.5.2",
    "express": "~4.14.0",
    "morgan": "~1.7.0",
    "serve-favicon": "~2.3.0"
  }
}

在推送应用程序时登录:

推荐答案

在您的package.json中似乎缺少引擎:

It seems like engines are missing in your package.json:

"engines": {
    "node": "6.7.0",
    "npm": "3.10.3"
  }

另外，部署Procfile可能会有所帮助:

Also deploying a Procfile can be helpful:

web: node ./bin/www

确定要部署整个文件夹吗?检查您的日志:

Are you sure you are deploying the entire folder? Check your logs:
