我有一个带有keystonejs框架的简单cms。当我做出一个提交，然后在azure中触发一个部署时，它的部署就失败了。
我使用的是标准层上运行的azure应用程序服务。
以前有个问题 Node-gyp 在Windows上，但根据这个，它已经修好了。
目前，我正在求助于做ftp部署。
我不太熟悉node，所以不确定诊断问题的最佳步骤是什么。
这是package.json

{
  "name": "MyApp",
  "version": "0.0.0",
  "private": true,
  "dependencies": {
    "keystone": "^0.3.22",
    "async": "^1.5.0",
    "lodash": "^4.13.1",
    "dotenv": "^2.0.0"
  },
  "devDependencies": {
    "eslint": "^2.12.0",
    "eslint-config-keystone": "^2.3.1",
    "eslint-plugin-react": "^5.1.1",
    "gulp": "^3.7.0",
    "gulp-shell": "^0.5.0",
    "gulp-watch": "^4.3.5"
  },
   "engines": {
    "node": "6.7.0",
    "npm": "3.9.5"
  },
  "scripts": {
    "lint": "eslint .",
    "start": "node keystone.js"
  }
}

这是在kudu上安装npm的输出
