title: d.ts files cannot find module 'rxjs/Observable'
body: <p>I am pretty new to Angular2/4 and i am trying to build a WebAPI that updates a SQL table. The Issue is that when I run the Build function in Visual Studio 2015, I get error code TS2307 "Cannot find module 'rxjs/Observable'" for every one of the "d.ts" files. When I click on the error, it sends me to the Import statement in the Specified file, with the error under the "@rxjs/Observable" portion.</p>
  
  <p>I have looked for a couple hours trying to find a solution and haven't found one that matches the situation, so if I duplicated something please drop a link in the comments so I can check it out. </p>
  
  <p>If there are any other files you would need to help please let me know. Thank you in advance. </p>
  
  <p>Here are some(as many as I could get in the screenshot)of the errors from VS15:

  <p><strong>UPDATE:1</strong>
  I went through and lowered the angular version number in the package.json file as shown above. Then deleted the node_module from the project and restarted VS15. then I restored the packages to find a bunch more errors waiting. </p>

  So I am hoping the new batch of errors helps figure something out... </p>
