如何获得 Angular 版本? [英] How to get the Angular version?

问题描述

我使用以下命令通过 npm 安装了 @angular/cli 包:

I installed the @angular/cli package via npm using:

npm install -g @angular/cli

@angular/cli 1.4.2 版本已经安装成功.那不是 Angular 版本，而是 CLI 版本.

The version 1.4.2 of @angular/cli has been successfully installed. That is not the Angular version, but the CLI version.

运行 ng new myapp 后，如何检查创建的应用程序使用的是哪个 Angular 版本?2.x、4.x?

After running ng new myapp how can I check which Angular version the created app is using? 2.x, 4.x?

推荐答案

ng version

您全局安装了 angular cli(命令中的 -g).这意味着您可以在命令提示符中键入 ng version.当您的命令提示符不是在 npm 控制的目录中时，这样做可能更精确(您应该在您输入的目录中输入ng new myapp).

You installed angular cli globally (-g in the command). This means that you can type ng version into your command prompt. It may be more precise to do this when your command prompt is not within a npm controlled directory (you should type this in within directory you typed ng new myapp).

给那些从 Google 来到这里的人的说明: ng version 会让你知道当前目录引用了哪个(粗略)版本的 Angular.例如此目录似乎安装了 angular 4.x (~4.3.0).

A note to those who got here from Google: ng version will let you know which (coarse) version of Angular is referenced by the current directory. e.g. This directory appears to have angular 4.x (~4.3.0) installed.

@angular/cli: 1.2.1
node: 8.11.1
os: win32 x64
@angular/common: 4.3.0
@angular/compiler: 4.3.0
@angular/core: 4.3.0
@angular/forms: 4.3.0
@angular/http: 4.3.0
@angular/platform-browser: 4.3.0
@angular/platform-browser-dynamic: 4.3.0
@angular/router: 4.3.0
@angular/cli: 1.2.1
@angular/compiler-cli: 4.3.0

如果您不在一个包含 packages.config 的目录中，那么您将获得 Angular: ....

If you are not within a directory which has a packages.config, then you will get Angular: ....
