Typescript version does not update

Question

I am running the following command to update my TypeScript version from 1.8.5 to 2.0.7 :

npm install -g typescript

it shows as -- [email protected]

Afterwards, when I am trying to check it manually using : tsc --version, it shows me : Version 1.8.5

Please tell me how to upgrade version of typescript from Version 1.8.5 to 2.0.7.

Do you have any other version of typescript installed, like from Visual Studio? If not, go into the global packages directory and remove everything typescript and reinstall — Dave V

Try uninstalling your existing typescript package(s) by executing npm uninstall -g typescript and then try installing the same like how you tried it eariler. — David R

Check from which folder tsc being executed. Windows: where tsc, Unix: which tsc. Maybe there is another tsc on your path before npm's. — goenning

Down load "TypeScript_Dev12.exe" and run it.

After successfully installing, you will find "C:\Program Files (x86)\Microsoft SDKs\TypeScript\2.0" in your system. Copy that path.

Now go to Environment Variables->System Variables->Path, now click on edit. Remove old path of type script and add new path over there.

Now restart your system. You will now find 2.0 as your typescript version.

Megha shah is right, but I think is better to install via npm globally

npm install typescript -g

and so use the existing C:\Users{username}\AppData\Roaming\npm.
