问题描述

现在， Angular正在遵循语义版本控制，并且 Angular2 .4.3已发布，我在升级到现有项目的下一个Angular版本时的最佳做法感到有些困惑.

Now that Angular is following a Semantic Versioning, and Angular2.4.3 were released, I'm a little confused here on what is the best practice when I upgrade to the next Angular version in existing project.

我有一个使用@angular/core: 2.2.0的Angular-cli项目.这是我的package.json:

问题:如何按照最佳做法升级到下一个Angular版本(现在:2.4.3或4.0.0-beta.3)?使用npm或yarn.

Question: How do I upgrade to the next Angular version(now: 2.4.3 or 4.0.0-beta.3) following the best practice? Using npm or yarn.

推荐答案

我已经将我的应用程序从Angular 2.4.0升级到了4.0.2，没有任何代码更改！请记住，尽管这取决于您使用的功能/类/方法.

I've upgraded my app from Angular 2.4.0 to 4.0.2 without any code changes! Bare in mind, though that it depends of which features/classes/methods you are using.

我跑了

npm i @angular/common@latest @angular/compiler@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest typescript@latest --S -E

然后

npm i @angular/compiler-cli@latest --D -E

注意:如果需要最新的稳定版本，请使用@latest.如果需要最新的出血边缘"版本，请使用@next.

NOTE: use @latest if you want the latest stable version. Use @next if you want the latest 'bleeding edge' version.
