FWIW, I just encountered this and was able to resolve it by updating NativeScript and installing TypeScript globally.

I have the same issue
npm install nativescript-toolbox or tns plugin add nativescript-toolbox get the error:

Try and run tsc on its own, you may have some errors in your project.

In my case I was trying to install nativescript-toolbox whilst I had some bad code (I removed a library then immediately tried to install nativescript-toolbox).

Fixing my code then re-running the install worked for me.
