Question

我的应用在本地工作。我添加了我认为Heroku必要的所有内容

Procfile

web: node app.js

的package.json

{
  "name": "HipsterMatch",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "nodemon app.js"
  },
  "dependencies": {
    "express": "3.1.0",
    "jade": "*",
    "mongodb": "*",
    "nodemon": "0.7.10",
    "passport": "*",
    "passport-local": "*",
    "passport-facebook": "*",
    "mongoose": "~3.6.4",
    "connect-flash": "*"
  },
  "engines": {
    "node": "0.10.1",
    "npm": "1.3.14"
  }
}

这是我的日志

Answer 1

看起来你正在引用你的本地mongoDB实例：

Error: failed to connect to [localhost:27017]

我想你已经对这些价值进行了硬编码......

处理从环境变为环境的连接字符串的推荐方法是使用环境变量（http://12factor.net/config）。

所以你需要做以下事情（如果你还没有）。

1）在云中设置一个mongo实例（MongoHQ，mongoLab等）（heroku使这相当容易）。

2）如果heroku没有为连接字符串设置env变量，那么你需要这样做。

列出你的环境（在命令行中输入）：

heroku config -a name_of_your_heroku_app

设置您的环境：

heroku config:set MONGO_URL=somethingGoesHere -a name_of_your_heroku_app

然后在您的节点代码中，您可以像这样引用该值：

var url = process.env.MONGO_URL;

要在本地设置env变量，请在应用的根目录中创建.env文件。运行foreman start将运行您的procfile以及将.env变量加载到内存中。
