404: '@angular/src' is not in the npm registry?
<p>I'm getting several 404 errors displayed my chrome devtools Console when I try to run my .NET website with Angular 2. Most of the console errors seem to have the following root cause: </p>

<p>Not found: package "@angular/src"</p>

<p>Here's 1 url returned in the console that returns the error:</p>

<p><a href="https://npmcdn.com/@angular/src/common_directives" rel="nofollow">https://npmcdn.com/@angular/src/common_directives</a></p>

<p>I did a text search in my app and no results are returned for "common_directives" so I'm guessing that this is reference is probably made as a dependency from some other reference. Have you seen this error before?  Any idea how to debug?</p>

<p>I tried:</p>

<p>npm i @angular/src --save</p>

<p>However this returns the following error:</p>

<p>'@angular/src' is not in the npm registry</p>
