Visual Studio Code doesn't recognize TypeScript module from `node_modules`

Question

Cloned the tslint repository, did npm install and grunt, as told in the README, and opened the folder in Visual Studio Code (0.9.1). Looking at any .ts file - src/rules/typedefRule.ts, say - gives TypeScript errors on require "typescript": Cannot find module 'typescript'.

The typescript module is in the node_modules folder, but VSC doesn't seem to know about that. How do I tell it to?

Have you run npm install -g typescript?

Yes. I should also add that I'm on OSX 10.11.

Two things:

The current version of typescript that vscode uses doesn't support typings lookup. You will need to update it to latest (typescript nightly) using the tssdk setting
The current typescript used by tslint (1.6.2) doesn't have typings field. You need to update tslint as well (a much bigger task).

Suggestion: Follow the other steps in readme and use THEIR definition file : https://github.com/palantir/tslint#custom-rules

I'm having (what I believe to be) a similar issue whereby VS (0.9.1) code doesn't recognise a module in node_modules/ and thus I get error highlighting and no Intellisense for the imported module. I've updated vscode's tssdk setting to path/to/typescript_1.6.2/lib/ doesn't seem stop the errors relating to module imports or Intellisense for those imported modules. (Note that after the tssdk changes Intellisense within the file still works.) Could you perhaps elaborate on your first bullet point? Does TS 1.6.2 support typings lookup?
