Error on `npm start`

After `npm install`, when I run `npm start`, I see

```
> babel-node ./src/countryInfo/test.js

internal/modules/cjs/loader.js:969
  throw err;
  ^

Error: Cannot find module '[home]/giojs/src/countryInfo/test.js'
```

It seems that `./src/countryInfo/test.js` is not in the repository, but `npm start`'s script points to it.
