nodemon，ts-node，不自动重新编译

Question

I am trying to create rest-api using, express+ts-node. I have done all setup based upon online tutorials, and when I run app using npm run dev it is working perfectly. But it is not restarting OnSave. This is my package.json script tag:

  "scripts": {
    "dev": "npm run nodemon src/index.ts",
    "nodemon": "nodemon --watch 'src/**/*.ts' --ignore 'src/**/*.spec.ts' -r ts-node/register/transpile-only -r tsconfig-paths/register -r dotenv/config --exec ts-node --files src/index.ts",
    "swagger": "tsoa spec"
  },

Looks like nodemon not watching file changes. Please help, how to do restart on save.
