Okay. Everything is working fine now.

I did what you said.

1. remove tsc, ttsc, ts-node and mocha globally
2. delete node_module folder
3. run npm install again
4. npm run test now works fine

Thank you

After removing global packages (I’d don’t recommend use global packages at all) run npm install again to verify that everything is installed properly.
