Cannot find namespace NodeJS

Question

I'm using Ionic2 and socket.io

When I do ionic serve I get this error in the terminal:

TypeScript error: typings/globals/socket.io/index.d.ts(357,30): Error TS2503: Cannot find namespace 'NodeJS'.
TypeScript error: typings/globals/socket.io/index.d.ts(739,28): Error TS2503: Cannot find namespace 'NodeJS'.

Node version is 4.2.6

My typings.json looks like this:

{
  "dependencies": {},
  "devDependencies": {},
  "globalDependencies": {
    "es6-shim": "registry:dt/es6-shim#0.31.2+20160602141504",
    "socket.io": "registry:dt/socket.io#1.4.4+20160317120654",
    "socket.io-client": "registry:dt/socket.io-client#1.4.4+20160317120654"
  }
}

If I open typings/globals/socket.io/index.d.ts (with sublimeText) I see this :

As you can see also sublimeText complains about NodeJS namespace.

Had a similar issue with a Node Typescript project. Turns out I just didn't have Node set as a global dependency.

typings install dt~node --global --save-dev

shortcut:

typings i -GD dt~node

Could you provide your typings.json?

Try to update to the latest commit 7de6c3dd94feaeb21f20054b9f30d5dabc5efabd

I also had same problem (with different namespaces), update fixed it.

EDIT: Try:

"socket.io": "github:DefinitelyTyped/DefinitelyTyped/socket.io/socket.io.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd",
"socket.io-client": "github:DefinitelyTyped/DefinitelyTyped/socket.io-client/socket.io-client.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
