d.ts文件找不到模块“ rxjs / Observable”

Question

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.

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.

If there are any other files you would need to help please let me know. Thank you in advance.

Here are some(as many as I could get in the screenshot)of the errors from VS15: Here is my Package.json file:

   {
     "version": "1.0.0",
     "name": "asp.net",
     "private": true,
     "scripts": {
           "build": "webpack",
           "start": "static ."
           },
     "dependencies": {
           "@angular/core": "2.4.0",
           "@angular/common": "2.4.0",
           "@angular/compiler": "2.4.0",
           "@angular/platform-browser": "2.4.0",
           "@angular/platform-browser-dynamic": "2.4.0",
           "core-js": "^2.4.1",
           "zone.js": "^0.8.4",
           "rxjs": "^5.2.0",
           "reflect-metadata": "^0.1.10"
           },
     "devDependencies": {
          "gulp": "^3.9.1",
          "gulp-exec": "^2.1.3",
          "awesome-typescript-loader": "^3.1.2",
          "typings": "^2.1.0",
          "webpack": "^3.8.1",
          "ng2-bs3-modal": "0.10.4"
          }
      }

Here is my tsconfig.json

  {
   "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "lib": [ "es2015", "dom" ],
        "noImplicitAny": true,
        "suppressImplicitAnyIndexErrors": true
        }
   }

UPDATE:1 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.

So I am hoping the new batch of errors helps figure something out...

Answer 1

On the advice of @yms , I found the Quickstart file for the Angular2.4 and copied the package.json, tsconfig.jason and systemjs.config.js into the solution. then i read the ReadMe file which points out that you have to use the angular/cli from now on.. so i tried installing that with the command:

npm install -g @angular/cli

my errors i was getting reduced to "incorrectly extends" error, which was fixed by pushing the typescript version to "^2.4.0" and the rxjs version to "5.4.2" in the package.json file then restoring the packages.

So here is my working Package.json:

对于MAC，我可以通过以下方法解决此问题：

sudo npm install -g --unsafe-perm --verbose @angular/cli
