Error: Cannot find module with ts-node

[daition]

Expected Behavior

"ts-node test.ts" should print "hello"

Actual Behavior

Error: Cannot find module

I'm not sure where is wrong. tsc works well but ts-node can't resolve the module "testModule" which is declared with "declare module" in a d.ts.

Steps to reproduce the problem

1. ts-node 9.1.1; node 14.15.5;tsc 4.2.3
2. at same directory, I have three files test.ts, testModule.d.ts, testModule.js

• testModule.js

function testMethod(){
console.log("hello")
}
module.exports={testMethod};`

• testModule.d.ts

declare module "testModule" {
export function testMethod():void;
};

• test.ts

import * as t from "testModule"; t.testMethod();

• tsconfig.json

{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"allowJs": true,
"strict": true,
"noImplicitAny": false,
"esModuleInterop": true,
"outDir": "./out",
"moduleResolution": "node",
"skipLibCheck": true,
"forceConsistentCasingInFileNames": true,
"baseUrl": ".",
"paths": {"testModule":["testModule.js"]},
"typeRoots": ["./node_modules/@types"],
"traceResolution":true
},
}

3. then, "ts-node test.ts" will give error

Error: Cannot find module 'testModule'
