TSError: ⨯ Unable to compile TypeScript - node.js

Question

My Project is built on Nodejs with TypeScript
I'm getting this compilation error in my Node.js app:
E:\NodeProjects\esshop-mongodb-nodejs\node_modules\ts-node\src\index.ts:859
return new TSError(diagnosticText, diagnosticCodes, diagnostics);
TSError: ⨯ Unable to compile TypeScript:

My problem solved by change this options in tsconfig.json:
"esModuleInterop": true,
"moduleResolution": "node",
"allowSyntheticDefaultImports": true
This worked for me
my tsconfig.json file :
{
"compilerOptions": {
"sourceMap": true,
"target": "es2019",
"outDir": "./dist",
"baseUrl": "./src",
"alwaysStrict": true,
"noImplicitAny": true,
"experimentalDecorators": true,
"emitDecoratorMetadata": true,
"esModuleInterop": true,
"moduleResolution": "node",
"allowSyntheticDefaultImports": true,
},
"include": [
"src/**/*.ts"
],
"exclude": [
"node_modules"
]
}
