Install and Set up Mongoose Express Error

JavaScript

Hi,

Here to report a potential issue and I am hoping to be replied if I am correct or not. I am trying the Install and Set Up Mongoose challenge but it returns the following error code:

Error: Cannot find module 'express'

npm WARN Local package.json exists, but node_modules missing, did you mean to install?

I think it has something to do with the server.js which we are not suppose to modify?

Hello @kwan19961217 ,

I have moved your reply to its own topic, as it is not related to the thread you posted in.

That error is saying that express is not installed. Sometimes, Repl does not automatically install the packages on a new project. So, you need to do it by running npm install within the shell terminal of your Repl.

Hope this clarifies.
