Cloud Functions Firebase CLI predeploy error (typescript)

I´m trying Cloud Functions with typescript.
After successfully installed, added a trigger and tested deploy.

index.ts

import * as functions from 'firebase-functions';

export const createAccount = functions.auth.user().onCreate(event => {
    const user = event.data;
    console.log('user displayname', user.displayName);
    return;
});

command

firebase deploy --only functions

=== Deploying to 'project'...

i  deploying functions
i  functions: running predeploy script.

> functions@ build D:\vmbox\project\firebase\functions
> tslint -p tslint.json && ./node_modules/.bin/tsc

ERROR

'.' is not recognized as an internal or external command,
operable program or batch file.

Environment
firebase cli v3.16.0
node v6.11.2
npm v4.2.0
OS: Windows 10
terminal: powershell

///

Rollback to Javascript

I re-initiated functions with Javascript option, and also got errors when deploying.
I guess it may be related to a setup made by the cli for typescript.
Had to delete the "functions" option added to "firebase.json".

option deleted in firebase.json:

  "functions": {
    "predeploy": "npm --prefix functions run build"
  }

Make sure that when you are initializing the project and it ask you to install dependencies, you select yes, I thought I had to manually write the dependencies so i passed it but it does it for you. When I did it everything worked. I don't know if this had something to do with it but i also deleted the node modules folder and in the same folder started again from firebase init.

add this line to tsconfig within the functions folder: 

"typeRoots": [
  "node_modules/@types"
],

This is part of "compilerOptions" block worked for me

Sorry for the delay. Andrew's answer will work, but it makes the project now only work on Windows. For more information, you can check my GitHub answer here. TL;DR:

Change the scripts in your package.json to:

  "scripts": {
    "lint": "./node_modules/.bin/tslint -p tslint.json",
    "build": "./node_modules/.bin/tsc"
  }

Change predeploy hook in your firebase.json to:

{
  "functions": {
    "predeploy": "npm --prefix functions run lint && npm --prefix functions run build"
  }
}

Just replace inside the package.json this

"build": "./node_modules/.bin/tslint.cmd -p tslint.json && ./node_modules/.bin/tsc.cmd"

on this

"build": ".\\node_modules\\.bin\\tslint.cmd -p tslint.json && .\\node_modules\\.bin\\tsc.cmd"

and it will work on windows.
