Question

我在Angular 2中尝试Hello World，当我跑＃34; npm start＆＃34;它不起作用。我已经在package.json的脚本中定义了start但是start没有工作

这是我的package.json设置

{
  "name": "ng2-helloworld",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\"",
    "test": "echo \"Error: no test specified\" && exit 1",
    "lite": "lite-server",
    "tsc": "tsc",
    "tsc:w": "tsc -w",
    "typings": "typings",
    "postinstall": "typing install"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",

    "lite-server": "^2.3.0",
    "typescript": "^2.2.2",
    "typings": "^2.1.1"
  }
}

这是我的tsconfig.json设置

    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "none",
        "sourceMap": true,

        "noImplicitAny": false,
        "lib": ["es2015", "dom"]
    }
}

        "sourceMap": true,
        "emitDecoratorMetadata": true,
