ts-node does not load typings installed with npm

[ghost]

ts-node won't recognize typings installed via npm, such as npm install @types/node

to reproduce create a typescript file that imports or uses node modules or globals such as:

import * as path from 'path';
console.log(__dirname);

and run npm -D install @types/node and then ts-node test.ts This will result in these compile errors:

TSError: ⨯ Unable to compile TypeScript
test.ts (1,23): Cannot find module 'path'. (2307)
test.ts (2,13): Cannot find name '__dirname'. (2304)

Seems like a duplicate of #216.
