I'm going to start working on a react-native project with another developer, but i've worked on another project before this one and it ran on an android emulator without errors.

I cloned the project from https://github.com/ismail-benlaredj/ld-vetrinalive-reactnative and ran npm install which resulted in this error :

PS G:\Workspaces\React Native\ld-vetrinalive-reactnative> npm install

• I dont know if i should include the lengthy npm log or not ( let me know ).

The problem :

• i dont know how to interpret the error messages ( resolve the peer dependencies )
• the console suggests to use the flags : --force, or --legacy-peer-deps at my own risk, i'm hesitant about doing that because it says

... to accept an incorrect (and potentially broken) dependency resolution.

and it's the reason i'm asking for help here.

Similar questions on SOF :

React Native app's npm install fails due to conflicting versions of react and react-dom

What i've tried so far :

Most answers i saw online suggested that i update my global react-native-cli but according to the docs here they ask you to uninstall it.

Also some answers pointed to some environment variables not being set properly, this isnt the case for me, since my other projects work fine.

CodePudding user response：

Try this.

npm cache verify
rm -rf node_modules
rm package-lock.json
npm i

This will clean the npm cache and rebuild the package-lock.json and node_modules

If it doesnt work, let me know and i will clone the repo and take a look.
