Re-creating lodash library-choice of project enviroment

I decided to complete the re-creating lodash library

which is the last project in the intermediate javascript course path on computer using a text editor of my choice but every time I run the tests it throws an error saying it cannot find the module - Error cannot find module,
but when I run the test on the codecademy console it runs perfectly is there something I’m missing or that I didn’t do? I think this is important because at the end of the day we should be able to do this on our own computers on our own that’s the aim.

_.js is exported as a module. All the supporting files are in the test directory. They are individual tests that all require the assert module.
