如果你正在使用angular-cli，那么你可以通过输入很容易地检查它

ng -v

或者在Angular 8、在Terminal或Bash中使用ng v。注意:在工程项目目录下运行该命令。

你应该得到这样的东西:

angular-cli: 1.0.0-beta.24
node: 7.4.0
os: darwin x64
@angular/common: 2.4.3
@angular/compiler: 2.4.3
@angular/core: 2.4.3
@angular/forms: 2.4.3
@angular/http: 2.4.3
@angular/platform-browser: 2.4.3
@angular/platform-browser-dynamic: 2.4.3
@angular/router: 3.4.3
@angular/compiler-cli: 2.4.3

有很多方法，你检查角版本只是压抑的命令 提示(用于windows)并键入

1. ng version
2. ng v
3. ng -v

4. You can pakage.json file

5.You can check in browser by presing F12 then goto elements tab

关于subversion (x.x.x)的完整理解，请参阅angular文档angularJS和angular 2+

1. ng --version (For checking Installed Angular Version in system)

2. npm --version (For checking Installed NPM Version in system) 

3. node --version (For checking Installed Node Version in system) 

为了使用angular 4+，

在版本中 的 v

请注意ng -v选项在Angular 7+中不起作用。

你可以从终端使用angular 2之后的版本，

ng -v

有多种方法:

您可以从您的包中验证。json文件 使用如下命令:

的 --版本

上面的命令将导致以下输出:

Angular CLI: 7.0.3 Node: 9.4.0 OS: darwin x64 Angular: 7.0.1 ... animations, common, compiler, compiler-cli, core, forms ... http, language-service, platform-browser ... platform-browser-dynamic, router Package Version @angular-devkit/architect 0.10.3 @angular-devkit/build-angular 0.10.3 @angular-devkit/build-optimizer 0.10.3 @angular-devkit/build-webpack 0.10.3 @angular-devkit/core 7.0.3 @angular-devkit/schematics 7.0.3 @angular/cli 7.0.3 @ngtools/webpack 7.0.3 @schematics/angular 7.0.3 @schematics/update 0.10.3 rxjs 6.3.3 typescript 3.1.4 webpack 4.19.1

因此，Angular、Angular CLI、Node和许多其他包的版本都可以从这里验证。
