VSCode cannot find module ‘@angular/core’ or any other modules

My project was generated with Angular CLI version 1.2.6.

I can compile the project and it works fine, but I always get error in VSCode telling me:

cannot  find module '@angular/core'
cannot find module '@angular/router'
cannot find module .....

I have attached content of my tsconfig.json file this has been really frustrating for me, spending 2 hours to figure out what is wrong, I have also uninstalled and reinstalled the VSCode it doesn’t work.

Here is my environment specification:

@angular/cli: 1.2.6
node: 6.9.1
os: win32 x64
@angular/animations: 4.3.4
@angular/common: 4.3.4
