Question

我正在尝试使用mocha / chai / karma按照打字稿设计模式书进行测试。

但是我有这个错误：

> npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "run" "test"
> npm ERR! node v6.3.1 npm ERR! npm  v3.10.7 npm ERR! code ELIFECYCLE

我在这里缺少什么：

karma.conf.js

// Karma configuration

module.exports = function(config) {
  config.set({

  })
}

的package.json

{
  "name": "sample2",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "mocha",
     "cover": "istanbul cover node_modules/mocha/bin/_mocha"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "chai": "^3.5.0",
    "karma": "^1.6.0",
    "karma-chai": "^0.1.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-mocha": "^1.3.0",
    "mocha": "^3.2.0",
     "istanbul": "latest"
  }
}

mocha.js

chai.should();

我不认为任何其他文件是相关的

ReferenceError：未定义chai
