只需在命令中输入ng v即可

你会得到这样的结果

Angular CLI: 7.3.9
Node: 12.11.0

你可以从终端使用angular 2之后的版本，

ng -v

另一种方法是从@angular/core导入VERSION常量，然后转储到控制台:

console.log(VERSION.full); //5.2.11

适用于:

Angular 8参见docs Angular 7参见docs Angular 6参见文档。 Angular 5参见docs Angular 4参见docs

Angular 2和3不太确定。(如果有人能测试一下;网页不可用)

对于AngularJS 1。使用angular.version:

console.log(angular.version); //1.7.4

在angular cli的新版本中，[ng -v]将不起作用。你必须输入[ng version]。

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。
