This is true for pretty much any usage of ts-node, it must be installed alongside the desired TypeScript version (which is usually local and not global). Maybe there’s a way to phrase this so it’s clearer and doesn’t need to describe every usage. I would imagine it is installed locally 99% of the time because it’s a dependency of the project. Also, you can do -D for saving to dev.

@blakeembrey Yeah, that's a good point !

I changed the wording to be less specific to VS Code and replaced with npm -D but please feel free to dismiss the PR if you feel it adds confusion.

I would make it clearer that the "in your project" option is for when you want to use an IDE.

Installing ts-node and typescript globally works fine for people not using any IDE at all, I'm guessing that's why this is the common example. Part of making open source documentation good is keeping it as agnostic as possible, so that it's easier for every reader to digest.

Alternatively, in the readme, there is also a section on using ts-node in Visual Studio Code specifically, so perhaps a note could be added there saying "you must install ts-node and typescript locally".
