ERR_MODULE_NOT_FOUND

Expected Behavior

I am expecting ts-node to successfully compile and run. I also compile with tsc and then run the compiled code and it works fine, this is what is confusing me. why is it working with tsc and not ts-node? they use the same tsconfig so it shouldn't have a difference.

Actual Behavior

I get the following error:

C:\Users\Pietro\Documents\projects\bulletproof-backand\src>ts-node server.ts
C:\Users\Pietro\AppData\Roaming\npm\node_modules\ts-node\dist-raw\node-internal-modules-esm-resolve.js:366
    throw new ERR_MODULE_NOT_FOUND(
          ^

Hey👋 @pietro99, I would recommend you use this command

npm run ts-node -- filename.ts
