Question

如何使用angular-cli而不是angular 4创建角度2 app？

我的package.json：

  "dependencies": {
    "@angular/animations": "^4.0.0",
    "@angular/common": "^4.0.0",
    "@angular/compiler": "^4.0.0",
    "@angular/core": "^4.0.0",
    "@angular/forms": "^4.0.0",
    "@angular/http": "^4.0.0",
    "@angular/platform-browser": "^4.0.0",
    "@angular/platform-browser-dynamic": "^4.0.0",
    "@angular/router": "^4.0.0",
    "core-js": "^2.4.1",
    "rxjs": "^5.1.0",
    "zone.js": "^0.8.4"
  },
  "devDependencies": {
    "@angular/cli": "1.1.1",
    "@angular/compiler-cli": "^4.0.0",
    "@angular/language-service": "^4.0.0",
    "@types/jasmine": "2.5.45",
    "@types/node": "~6.0.60",
    "codelyzer": "~3.0.1",
    "jasmine-core": "~2.6.2",
    "jasmine-spec-reporter": "~4.1.0",
    "karma": "~1.7.0",
    "karma-chrome-launcher": "~2.1.1",
    "karma-cli": "~1.0.1",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",
    "karma-coverage-istanbul-reporter": "^1.2.1",
    "protractor": "~5.1.2",
    "ts-node": "~3.0.4",
    "tslint": "~5.3.2",
    "typescript": "~2.3.3"
  }

我试图更改角度版本，但它仍然无法正常工作

Answer 1

在你的package.json中 - ＆gt; dependencies数组将角度版本更改为2.4.1并重建项目。

详细答案： -

1）使用Cli创建新项目。

ng new my-newapp

2）将目录更改为

cd my-newapp

3）更新package.json - ＆gt;依赖。将角度版本更改为2.4.1并将路由器更改为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）重新安装所有软件包（可选： - 在执行此命令之前，您可以删除node-module文件夹）

npm install

5）启动浏览器

ng serve

注意： - 在执行ng服务时，我的系统面临问题

ERROR in AppModule is not an NgModule

您通过向app.module.ts添加空行来解决此问题。

使用角度2代替角度4和角度cli
