Requiring built-in modules throws an error

[chrissantamaria]

Not sure if I'm missing something here - requiring standard NPM modules works as expected (such as const axios = require('axios')) but any built-in module such as fs or querystring fails:

node v12.4.0 [email protected] [email protected]
Type `> jay.help()` in the prompt for more information.
> const fs = require('fs')
C:\Users\Chris\AppData\Local\Yarn\Data\global\node_modules\jay-repl\dist\moduler.js:158
            throw new Error(`\`${id}\` has an invalid \`package.json\` file`);
            ^

I'm on Windows 10 and installed jay globally with Yarn.

definitely shouldn't be happening, thanks.

fyi - just like in the vanilla node repl - all built-in modules are available by default, there's no need to require them.
