找不到模块：无法解析“C:\Users\user\Desktop\react-challenge\sample\src”中的“./App”

Question

I am learning react from a playlist and had created a basic app with create-react-app it was up and running without any issues initially. After I deleted some files in ' src ' and ' public ' ,the terminal is showing this error:

./src/index.js
Module not found: Can't resolve './App' in 'C:\Users\user\Desktop\react-challenge\sample\src'

I deleted everything except for 'index.html' in public and 'index.js' in src file. I have attached the folder structure and index.js below.

EDIT: it was an issue regarding the files getting saved and reloading it is solved now.

Answer 1

It's fine to delete App.js if you're not using it, and it looks like you're not. You probably just need to restart your development server.

Stop it with Ctrl + C
Start it again with npm start or yarn start

Answer 2

power off your code editor and start again the code editor then run npm start in the terminal
