[ac5tin]

@ac5tin is the issue still present?

FYI for ts-node you can add settings in tsconfig:

  "ts-node": {
    "transpileOnly": true,
    "compilerOptions": {
      "module": "commonjs"
    }
  },

[talentlessguy]

@ac5tin it still doesn’t seem to be related to milliparsec directly

I don’t know how to help you here

worth asking on tsconfig-paths repo instead
