我有我的老项目，使用Ember 2.8。
现在，我想更新所有的包，这是更新后的package.json

{
  "name": "php-api-ember-test",
  "version": "0.0.0",
  "description": "Small description for php-api-ember-test goes here",
  "directories": {
    "doc": "doc",
    "test": "tests"
  },
  "scripts": {
    "build": "ember build",
    "start": "ember server",
    "test": "ember test"
  },
  "repository": "",
  "author": "",
  "license": "MIT",
  "devDependencies": {
    "broccoli-asset-rev": "^2.4.5",
    "ember-ajax": "^3.0.0",
    "ember-cli": "~2.14.2",
    "ember-cli-app-version": "^3.0.0",
    "ember-cli-babel": "^6.3.0",
    "ember-cli-bootstrap-4": "^0.3.2",
    "ember-cli-dependency-checker": "^1.3.0",
    "ember-cli-eslint": "^3.0.0",
    "ember-cli-htmlbars": "^2.0.1",
    "ember-cli-htmlbars-inline-precompile": "^0.4.3",
    "ember-cli-inject-live-reload": "^1.4.1",
    "ember-cli-jshint": "^1.0.0",
    "ember-cli-qunit": "^4.1.0",
    "ember-cli-release": "^0.2.9",
    "ember-cli-sass": "5.5.1",
    "ember-cli-sri": "^2.1.0",
    "ember-cli-test-loader": "^1.1.0",
    "ember-cli-uglify": "^1.2.0",
    "ember-data": "~2.14.9",
    "ember-export-application-global": "^2.0.0",
    "ember-load-initializers": "^1.0.0",
    "ember-resolver": "^4.0.0",
    "ember-welcome-page": "^3.0.0",
    "loader.js": "^4.2.3"
  },
  "engines": {
    "node": "^4.5 || 6.* || >= 7.*"
  },
  "private": true
}

这位是bower.json

{
  "name": "php-api-ember-test",
  "dependencies": {
    "ember": "~2.14.0",
    "ember-cli-shims": "0.1.1"
  }
}

我删除了bower_components和node_modules文件夹，然后运行命令npm install && bower install。在这些安装完成后，我运行ember init并得到此结果。

Run `npm install` to install missing dependencies.

An error occured in the constructor for ember-cli-dependency-checker

但是我已经运行npm install命令很多次了。
如何更新Ember软件包？
