ts-node-esm eval works differently to ts-node-esm with a file. Eval gives "Cannot use import statement outside a module"

[jsalli]

I wondering why ts-node-esm gives an "Cannot use import statement outside a module" error.

Expected Behavior

MYCODE=$(cat "./src/testCode.ts") && echo $MYCODE | npx ts-node-esm
Prints: /first/second

npx ts-node-esm -e 'import { parse } from "path";const output: string = parse("/first/second/file.ts").dir; console.log(output);'
Prints: /first/second

Actual Behavior

// Both give the below output
/home/juha/workspace/testent/simple-typescript-project-example/[stdin].ts:1
import { parse } from 'path';
^^^^^^
SyntaxError: Cannot use import statement outside a module

Minimal reproduction

• ./src/testCode.ts

// ./src/testCode.ts
import { parse } from 'path';
const output: string = parse('/first/second/file.ts').dir;
console.log(output);

• tsconfig.json

// tsconfig.json
{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "lib": ["ESNext"],
    "outDir": "dist",
    "esModuleInterop": true,
    "sourceMap": true,
    "declaration": true,
    "strict": false,
    "noImplicitAny": false,
    "noUncheckedIndexedAccess": false,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "useUnknownInCatchVariables": false,
    "skipDefaultLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "incremental": true,
    "moduleResolution": "node",
    "noUnusedLocals": false,
    "skipLibCheck": true,
    "useDefineForClassFields": true,
    "experimentalDecorators": true,
  },
  "include": ["src/"],
  "exclude": ["**/dist", "**/node_modules", "**/src/__tests__"]
}

• package.json

// package.json
{
	"name": "simple-typescript-project-example",
	"type": "module"
}

Node version

Node: v16.17.0

Ways which work

This on the other hand works and it's exactly the same code, just without the eval.
npx ts-node-esm ./src/testCode.ts

If I change package.json "type" to "commonjs" and tsconfig.json compilerOptions.module to "CommonJS" then the both npx ts-node-esm -e .... and MYCODE=$(cat "./src/testCode.ts") && echo $MYCODE | npx ts-node-esm work.

Does anyone know what is the reason for the different behavior between eval and "normal" execution with ts-node-esm when package.json "type" is "module" and tsconfig.json compilerOptions.module is "ESNEXT"?

How could I make the MYCODE=$(cat "./src/testCode.ts") && echo $MYCODE | npx ts-node-esm work when package.json "type" is "module" and tsconfig.json compilerOptions.module is "ESNEXT" (Or not "Commonjs" or "NodeNext")?
