how to run an existing project of react native

Question

I wanted to download and run someone else's project in order to consider its functions. I ran into a number of problems ... that it does not deign to start, and I just don’t know what to do, help, please

https://github.com/sunlight3d/react_native_v0.49/tree/master/61-Realm%20React%20Native%235.Filter%20data%20and%20working%20with%20To-Many%20Relationships/code/tutorialProject

1) copied to the working folder tutorial project

2) opened VS code

3) went into the working folder and clicked open in cmd folder tutorial project

4) then I enter react-native run-android and get fiasco

d:\JS\tutorialProject>react-native init tutorialProject
 internal/modules/cjs/loader.js:657 throw err; ^

 Error: Cannot find module 'graceful-fs' at

I started googling and found something to do with some dependencies. Using react-native init MyProject

5) react-native init tutorialProject and getting the tighter right line

I try to start the server through npm and then it's funny ... 6) npm-intall

d:\JS\tutorialProject>npm install npm WARN deprecated [email protected]:
 core-js@<2.6.5 is no longer maintained. Please, upgrade to core-js@3
 or at least to actual version of core-js@2. npm WARN deprecated

Answer 1

When you download after you need to install all package in package.json

npm install --save

then you need to start another terminal

npm start -- --reset-cache / npm start / react-native start 

It's for starting your bundler

finally you can run your project

react-native run-android
