Description

I was in a project, and forgot that I deleted node_modules (or forgot to npm install), and in this case I was seeing any all over the place, and was jumping myself to conclusions that something was wrong with TypeScript or VS Code.

It could be helpful if VS Code could suggest something like

Did you forget to install dependencies? Perhaps you should run npm install?

or similar.
