Question

running command in terminal node ./src/index.ts i get this error.
import * as yargs of 'yargs': SyntaxError: Cannot use import statement outside of module
What's the problem? How to fix it?

Answer 1

Compile the project. Well, it's generally, since you have a typescript file, I assume that you will use the features of the typescript.
And if specifically about ES6-style imports, then the --experimental-modules key and the .mjs extension, or the type:module field in package.json will solve the problem.

Answer 2

install (can be globally)
https://www.npmjs.com/package/ts-node
and run from it
