If you are on Windows and have Visual Studio installed you might have something in your PATH that is pointing to an old version of TypeScript   I found that removing the folder  C  Program Files  x86  Microsoft SDKs TypeScript 1 0   from my PATH  or deleting renaming this folder  will allow the more recent npm globally installed TypeScript version of tsc to work

For npm  you can run  npm update -g typescript  By default  it will install latest version  For yarn  you can run  yarn upgrade typescript  Or you can remove the orginal version  run yarn global remove typescript  and then execute yarn global add typescript  by default it will also install the latest version of typescript  more details  you can read yarn docs

You should be able to do this by simply typing npm install -g typescript 2 0  If this does not work  I am beginning to wonder what version of node and npm you are on  Try node -v and npm -v to find these out  You should be on node  4 5 and npm  3

Open command prompt  cmd exe git bash  Recommended  npm install -g typescript latest  or yarn global add typescript latest     if you use yarn package manager  This will install the latest typescript version if not already installed  otherwise it will update the current installation to the latest version  And then verify which version is installed  tsc -v    If you have typescript already installed you could also use the following command to update to latest version  but as commentators have reported and I confirm it that the following command does not update to latest  as of now   Feb 10  17    npm update -g typescript latest
