使用npm install angular2 –save时出错
我正在关注Angular 2上的Tuts +教程。在这个video中： https : //code.tutsplus.com/courses/whats-new-in-angular-2/lessons/angular-2-and-es5作者说input以下命令：
npm install angular2 --save
我试过了，以及在它前面使用sudo ，但得到以下错误：

想法？
作者能够没有错误地做到这一点：
要使用npm安装angular2，您可以指定版本或使用@latest
- 指定一个版本
npm install angular2@2.0.0-beta.1 --save
- 使用
latest（这将显然安装在npm提供的最新版本）
npm install angular2@latest --save
还要注意的是，有计划支持angular@next来增加安装夜间构build的可能性，但是它还不被支持（到目前为止，快照是不时发布的，但命令还没有提供）。 检查问题＃4671了解更多信息。
