Angular CLI 是 Angular 的一个命令行工具，可以便捷的执行创建项目、创建文件、测试、打包和发布等任务。

### Angular 版本 ###

Angular 2.x及以上统称`Angular`, Angular 1.x 则称为 `AngularJS`.

Angular 5 发布于 2017年11月01日。  
Angular 6 发布于 2018年05月03日。  
Angular 7 发布于 2018年10月18日。

### 安装 Angular CLI ###

$ npm install -g @angular/cli

### 使用ng update命令更新Angular ###

使用 `ng update` 命令查看更新:

$ ng update
    We analyzed your package.json, there are some packages to update:
      Name             Version          Command to update
     -----------------------------------------------------------
      @angular/cli     7.1.1 -> 7.1.2   ng update @angular/cli
      @angular/core    7.1.1 -> 7.1.2   ng update @angular/core
    
    There might be additional packages that are outdated.
    Run "ng update --all" to try to update all at the same time.

使用 `ng update` 更新 `@angular/cli` 包:

$ ng update @angular/cli
        Updating package.json with dependency @angular/cli @ "7.1.2" (was "7.1.1")...
    UPDATE package.json (1528 bytes)
    updated 10 packages in 18.119s

再次查看:

$ ng update
    We analyzed your package.json, there are some packages to update:
      Name             Version            Command to update
     --------------------------------------------------------------
      @angular/core    7.1.1 -> 7.1.2     ng update @angular/core
    
    There might be additional packages that are outdated.
    Run "ng update --all" to try to update all at the same time.

使用 `ng update` 更新 `@angular/core` 包:

$ ng update @angular/core
    Updating package.json with dependency @angular/language-service @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/animations @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/compiler @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/compiler-cli @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/platform-browser-dynamic @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/router @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/platform-browser @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/common @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/http @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/forms @ "7.1.2" (was "7.1.1")...
    Updating package.json with dependency @angular/core @ "7.1.2" (was "7.1.1")...
    UPDATE package.json (1528 bytes)
    updated 11 packages in 48.459s

再次使用 `ng update` 检测，已经没有新的更新了。

$ ng update              
        We analyzed your package.json and everything seems to be in order. Good work!

使用 `ng v` 查看当前版本：

$ ng v
