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
OS: win32 x64
Angular: 7.2.15
... common, compiler, compiler-cli, core, f
... language-service, platform-browser, pla
... router

webpack                           4.29.0

只要通过terminal进入你的angular项目目录，然后ng -v给出所有信息

Angular CLI: 1.7.4
Node: 8.11.1
OS: linux x64
Angular: 5.2.11
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, router

@angular/cli: 1.7.4
@angular-devkit/build-optimizer: 0.3.2
@angular-devkit/core: 0.3.2
@angular-devkit/schematics: 0.3.2
@ngtools/json-schema: 1.2.0
@ngtools/webpack: 1.10.2
@schematics/angular: 0.3.2
@schematics/package-update: 0.3.2
typescript: 2.5.3
webpack: 3.11.0

如果你在angular项目目录外检查ng-v，那么它将只显示angular-cli版本。

现在是ng -v

如果你正在使用angular cli，那么你可以检查using

的 --版本

现在是ng -v

或者你也可以签到

行囊。json文件

 "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",
    "angular-in-memory-web-api": "^0.3.2",
    "core-js": "^2.4.1",
    "rxjs": "^5.1.0",
    "zone.js": "^0.8.4"
  },

你可以输入ng版本 这是它

你可以从终端使用angular 2之后的版本，

ng -v
