好的。你的问题是什么？这消息不是很清楚吗？ –

我是新来的角。我认为角2.0.0是角2的最新版本。如果我需要使用角2，什么是最新版本 – Tom

最新版本的Angular是1.4.3（请参阅https://github.com/angular/angular /blob/master/CHANGELOG.md）。我真的不明白为什么你会强迫你使用Angular的过时版本。 Angular 4和Angular 2是相同的框架。该版本因最小的重大更改而升级，就这些了。 –

您已保存您的角度版本2.0.0

您需要将您的角度依赖性升级到最新版本。

"dependencies": { 
    "@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/material": "^2.0.0-beta.6", 
    "@angular/platform-browser": "^4.0.0", 
    "@angular/platform-browser-dynamic": "^4.0.0",

Hi leon，我的客户不希望我在角度4上工作。我被告知只使用angular2 – Tom

我对版本 – Tom

有点困惑他们为什么不想使用角度4？这是“angular 2”的最新版稳定版。 –

此版本的cli只与角度版本2.3.1或更高版本兼容
