}

The error say ts-node-dev: no script to run provided, but I gave it:
set debug=* && ts-node-dev --respawn --inspect --transpileOnly ./src/index.ts

I am using the following options -

Dev dependencies :

"ts-node": "^10.9.1",
"ts-node-dev": "^2.0.0",
"typescript": "^5.0.4"

and script in package.json to start :

"start":"ts-node-dev --respawn ./index.ts",

It works for me.

That no script to run provided error is the slightly unhelpful way that ts-node-dev's behaves if it doesn't recognize an option. (This is true as far as v1.1.6, at any rate.)

The problem here is that it doesn't understand the --transpileOnly option. Possibly older versions did, because you see a few examples around the web with that option. But now you need to write --transpile-only.

You'd think it would say something like "Unrecognized option: --transpileOnly", but no.

(The answer from Emefile Francis Waje does include this change, but it's easily missed, because it also proposes two more changes: making ts-node-dev a dev dependency, and using npx. So when I first read that answer, I totally missed the change from --transpileOnly to --transpile-only because I was focusing on the other two changes. So I'm calling this detail out here in a separate answer because it's the root cause of the error that the question mentions.)

Try to run npm i ts-node-dev --save-dev, and modify your script to npx ts-node-dev --respawn --transpile-only --debug ./src/index.ts
