推荐答案

在您的 package.json -> dependencies 数组中将 angular 版本更改为 2.4.1 并重建您的项目.

In your package.json -> dependencies array change angular version to 2.4.1 and rebuild your project.

详细回答:-

1) 使用 Cli 创建新项目.

1) Create new project using Cli.

ng new my-newapp

2) 将目录更改为

cd my-newapp

3) 更新 package.json -> 依赖项.将angular版本改为2.4.1，将router改为3.4.1

3) update package.json -> dependencies. Change angular version to 2.4.1 and change router to 3.4.1

示例:-

{
  "name": "my-newapp",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
      "@angular/common": "2.4.1",
    "@angular/compiler": "2.4.1",
    "@angular/compiler-cli": "2.4.1",
    "@angular/core": "2.4.1",
    "@angular/forms": "2.4.1",
    "@angular/http": "2.4.1",
    "@angular/platform-browser": "2.4.1",
    "@angular/platform-browser-dynamic": "2.4.1",
    "@angular/router": "3.4.1",
    "@angular/upgrade": "2.4.1",
    "@angular/material": "2.0.0-beta.0",
    "bootstrap": "^3.3.7",
    "concurrently": "^3.1.0",
    "core-js": "^2.4.1",
    "hammerjs": "^2.0.8",
    "reflect-metadata": "^0.1.9",
    "rxjs": "^5.0.2",
    "systemjs": "^0.19.41",
    "zone.js": "^0.7.4"
  },
  "devDependencies": {
    "@angular/cli": "1.0.0",
    "@angular/compiler-cli": "^4.0.0",
    "@types/jasmine": "2.5.38",
    "@types/node": "~6.0.60",
    "codelyzer": "~2.0.0",
    "jasmine-core": "~2.5.2",
    "jasmine-spec-reporter": "~3.2.0",
    "karma": "~1.4.1",
    "karma-chrome-launcher": "~2.0.0",
    "karma-cli": "~1.0.1",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",
    "karma-coverage-istanbul-reporter": "^0.2.0",
    "protractor": "~5.1.0",
    "ts-node": "~2.0.0",
    "tslint": "~4.5.0",
    "typescript": "~2.2.0"
  }
}

4) 重新安装所有包(可选:- 在执行此命令之前，您可以删除 node-module 文件夹)

4) reinstall all package ( optional:- before execute this command you can delete node-module folder)

npm install

5) 启动浏览器

ng serve

注意:- 在我的系统中执行 ng serve 时遇到了问题

Note :- In my system while execute ng serve i faced issue

ERROR in AppModule is not an NgModule

您可以通过向 app.module.ts 添加一个空行来解决此问题.

you fix this issue by adding an empty line to the app.module.ts.
