Cannot find name 'HammerInput' and 'HammerManager'

[j-tee]

I installed Angular Material 2.0.0-alpha.10 alongside hammerjs@2.0.8 and @types/hammerjs@2.0.33.
Per the instructions, guidelines and suggestions, I imported hammerjs in my main.ts file but I could not get rid of the errors. After several weeks I thought I should import 'hammerjs' in the files containing the errors as well. After importing hammerjs in MdGestureConfig.d.ts all the errors disappeared. I really dont know what to make of this. So I thought I should ask the experts about it

I had the same error. I just needed to restart the server running from angular-cli then the 'HammerInput' and 'HammerManager' dependancies are resolved.

I just started work on getting the sidenav to work. Hoping I made the right call

@j-tee You need to include hammerjs in the types section of your tsconfig.json:

{
  "compilerOptions": {
    // other typescript options
    "types": [
      "hammerjs"
    ]
  }
}

I'll see how to make this clearer in the docs.
