I have an Angular2 project created with the angular-cli project templates in Visual Studio Code. Also, I installed the latest version of Typescript (2.0.3) via npm as well as via the Microsoft link (https://www.microsoft.com/en-us/download/details.aspx?id=48593) because I also use Visual Studio 2015. However, for some reason the I still get an error message when I start my Angular2 project. Note that even with a standard command prompt running tsc -v will still return 1.0.0.0.

  • How does tsc -v determine the version of typescript?
  • How do I get rid of this message in my Angular project and ensure it will be using the latest version of Typescript?

What am I missing here? Appreciate your help.

If you only need the last version of TypeScript, on both Visual Studios, then you can

  1. delete all previous installations which are located in:
    C:\Program Files (x86)\Microsoft SDKs\TypeScript.
  2. reinstall the latest TypeScript version.

Hopefully everything will work.

Thanks. Simply deleting the other versions has done the trick.

Did you install TypeScript via NPM? If this is the case, try uninstalling it via npm uninstall -g typescript. Now reinstall it via npm install -g typescript and check if the problem is solved.

The best way is to allow VScode to only use the version of typescript installed locally.

Drop this in your .vscode/.settings file.

    "typescript.tsdk": "./node_modules/typescript/lib"
