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

问题

Summary

I'm trying to install typescript typings for my web app, but I can't get command prompt to recognize the typings command.

The Problem

typings install throws the following error:

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

Details

When I run npm i typings -g, the console tells me the module has been installed. But when I look in my global npm directory, there is no typings file.

C:\gitdev\MyWebApp\src\main\webapp\myUI>npm i typings -g
C:\home\123456\AppData\Roaming\npm\typings -> C:\home\123456\AppData\Roaming\npm\node_modules\typings\dist\bin.js
C:\home\123456\AppData\Roaming\npm
`-- typings@2.1.1

More Details

my username has been replaced with 123456 for security purposes. everything else is copied verbatim.

I don't have admin privileges (i'm on a work machine)

where typings also throws an error (INFO: Could not find files for the given pattern(s).

npm -g worked fine for grunt-cli

npm is in my PATH as C:\Users\123456\AppData\Roaming\npm
