Install new version of TypeScript

In this article we are going to focus on how to install a new version of TypeScript if there is already an older version of typescript installed on your computer due to Visual Studio installation.

Open the command prompt and type tsc -v and then you will find the version of type script installed on your computer. I had version 1.0.3.0 installed and I would like to install the latest version of TypeScript.

Go to the environment variables on your computer and open the Path environment variable. Now remove the Type script path "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\;".


Delete the TypeScript folder from the "C:\Program Files (x86)\Microsoft SDKs" path. I saved this folder to another location on my computer just to ensure that if the new command does not work I can restore it back.

Now go to command prompt and type the following command:

npm install -g typescript


This will install the latest version of the TypeScript on your computer and you can confirm it using tsc -v command which displays the message as shown in the screenshot below.


Voila!! you now have a latest version of TypeScript installed.
