Question

我是Heroku的新手，我一直在尝试使用node.js部署Hello World应用。

问题是我有这个

error: failed to push some refs to 'https://git.heroku.com/sebasaenz.git'

但我真的不知道如何解决问题。通过以前的错误消息，它似乎与package.json文件有关，但我试图在文档中找到可能存在的问题，我真的不明白它是什么。

输入git push heroku master

后出现错误消息

我的package.json文件如下：

{
  "name": "hello-world",
  "version": "1.0",
  "description": "Node demo",
  "engines": {
    "node": "5.9.1"
  },
  "main": "index.js",
    "scripts": {
    "start": "node index.js"
  },
  "dependencies": {
    "ejs": "2.4.1" 
  }, //this is line 14 
  "repository": {
    "type": "git",
    "url": "https://git.heroku.com/sebasaenz.git"
  },
  "keywords": [
    "node",
    "heroku"
  ],
  "license": "MIT"
}

我已经找过具有相似特征的帖子，但我找不到任何可以帮助我的内容。

Answer 1

您提供的JSON中唯一无效的位是依赖项中"ejs": "2.4.1"和关键字数组中"heroku"之后的逗号。

Answer 2

我遇到了同样的问题。请注意来自heroku的这两行：

remote: parse error: Expected another key-value pair at line 14, column 3
remote:  !     Unable to parse package.json

package.json文件有问题。就我而言，我错过了一个括号，最后关闭了文件。请参阅以下示例：

{
  "name": "tempdeployment",

  "version": "1.0.0",
  "description": "This version of __ is for temporary deployment.",
  "main": "app.js",
  "scripts": {
    "test": "test.js",
    "start": "node app.js"
  },
  "author": "____",
  "license": "ISC",
  "dependencies": {
    "ejs": "^2.5.7",
    "express": "^4.16.2",
    "request": "^2.83.0"
  },
  "engines": {
    "node":"^8.9.4"
  }

请注意，此JSON文件缺少右括号。一旦我添加了括号，我就没有遇到任何问题。在您的情况下，看起来第14行的某个键值对存在问题。修复此问题，您的应用应该没有问题进行部署。

以下是我的package.json文件的更正版本：

{
  "name": "tempdeployment",

  "version": "1.0.0",
  "description": "This version of __ is for temporary deployment.",
  "main": "app.js",
  "scripts": {
    "test": "test.js",
    "start": "node app.js"
  },
  "author": "____",
  "license": "ISC",
  "dependencies": {
    "ejs": "^2.5.7",
    "express": "^4.16.2",
    "request": "^2.83.0"
  },
  "engines": {
    "node":"^8.9.4"
  }
}

Answer 3

mvn clean install

然后推送到heroku master。
