Question

我使用JetBrain Webstrom创建了一个NodeJS应用程序，现在我想将它部署到heroku。

我应该删除node_modules来部署应用吗？或者我应该添加任何＆＃34;引擎＆＃34; package.json下的部分？我该怎么做才能在heroku中正确部署我的应用程序。

我的应用程序的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"
  }
}

推送应用程序时记录：

Answer 1

尝试将此添加到package.json：

  "engines": {
    "node": "whatever_version_you_want"
  }

您不需要安装/删除node_modules，Heroku应该为您执行此操作。

Answer 2

您的package.json中似乎缺少引擎：

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

同样部署Procfile会很有帮助：

web: node ./bin/www

您确定要部署整个文件夹吗？检查你的日志：
