[ERROR] Must use import to load ES module

Issue description

Context

Totally new Node project with typescript, @types/node, and ts-node-dev packages installed. I only get this error when I set type: "module" in package.json.

ts-node-dev: ^2.0.0

OS version (is it docker or host?), ts-node-dev version

Did you try to run with ts-node?

Did you try to run with --files option enabled?

Did you try to run with --debug option enabled?

Do you have a repro example (git repo) with simple steps to reproduce your problem?

Update

Besides it working with Babel, I achieved to make it working with nodemon and ts-node.

Install nodemon and ts-node and of course typescript, set type: "module" in package.json, and set tsconfig.json to:

{
  "compilerOptions": {
    "esModuleInterop": true,
    "moduleResolution": "Node",
    "module": "ESNext",
    "target": "ESNext"
  }
}

And then: nodemon --exec node --loader ts-node/esm src/main.ts
