Question

我正在尝试将React项目部署到Heroku。以前没有问题，但现在有问题 - 我怀疑它是因为版本控制？对此仍然很新，所以可以在这里欣赏一些有用的信息。

终端错误消息：

的package.json：

{
  "name": "react-boilerplate",
  "version": "1.0.0",
  "description": "Minimal boilerplate for react",
  "main": "index.js",
  "engines": {

    "npm": "5.0.4"
  },
  "scripts": {
    "dev": "webpack-dev-server --progress --inline --colors --hot --config ./webpack.config.js",
    "postinstall": "NODE_ENV='production' webpack -p",
    "start": "node server.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",

  "babel": {

    ]
  },

    "babel-core": "^6.24.1",

    "react-redux": "^5.0.5",
    "redux": "^3.7.1",
    "redux-thunk": "^2.2.0"
  }
}

我怀疑这与我的node / npm版本有关吗？我最近更新了node或npm（无法记住哪一个），但之后我似乎遇到了部署问题。这是我在终端命令中注意到的：

remote: -----> Installing binaries
remote:        engines.node (package.json):  unspecified
remote:        engines.npm (package.json):   unspecified (use default)
remote:

remote:        Downloading and installing node 6.11.0...
remote:        Detected package-lock.json: defaulting npm to version 5.x.x

这里的主要问题是缺少模块webpack。这是因为它没有列在package.json中的dependencies属性中，该属性定义了生产环境中所需的模块。

要解决此问题，您应该将webpack放在dependencies内并将其从devDependencies中删除。

您还应该确保node_modules不包含在git存储库中。因此，在部署到heroku之前，应该在gitignore中包含node_modules并删除git存储库中的node_modules。
