npm - How to upgrade Typescript to the latest version?

Question

I have a MacBook Pro with OS X 10.8.2 Some time ago I installed Typescript and today I'd like to upgrade that installation to the latest version available (so far, v0.8.3). I wrote this command from the terminal:

sudo npm install -g typescript

But this is what I got on the display:

npm http GET https://registry.npmjs.org/typescript
npm http 304 https://registry.npmjs.org/typescript
/usr/local/bin/tsc -> /usr/local/lib/node_modules/typescript/bin/tsc
typescript@0.8.0 /usr/local/lib/node_modules/typescript

Does this means that I still have version 0.8.0 installed on my computer? I tried to see if the tsc command has a -v or a -version parameter but I haven't found it, so I still uncertain if I have upgraded Typescript to the latest release or if I'm still stuck with an older version.

Since selected correct answer didn't help me I figured I'd share how I resolved the issue.

I had to remove C:Program Files (x86)Microsoft SDKsTypeScript1.0 from my PATH.

After that I could run this command and see the version I was expecting:

C:>tsc --version
message TS6029: Version 1.5.3
