node.js — Как использовать & quot; require & quot; в приложении JXCore C ++

Я пытаюсь использовать JXCore для вызова некоторого кода node.js внутри моей программы на C ++. Я могу запустить мою программу на C ++ с прикрепленным кодом, если закомментирую строку: "var path = require('fs'); \n" Таким образом, я в основном сузил свою проблему до использования команды «require». Код работает, если я запускаю его непосредственно из jx. Я также использую Visual Studio, если это имеет значение. Как вы скажете jx, где находятся дополнительные модули, такие как ‘fs’?
