    Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Oct 05 '22 at 11:28
  • This is a very poor question, you just posted an error message without any commentary or discussion on what you tried to solve the error. The only other question you've asked is likewise a poorly structured question. Please read [this post on how to ask questions](https://stackoverflow.com/help/how-to-ask). – Nathan Oct 08 '22 at 20:06

This happens when the package you're installing has a different version compared to your local package. There are 2 ways to solve this issue.

The first way ( easy way )

Just do npm install packagename --legacy-peer-deps or npm install packagename --force

The second way ( hard way )

If the above doesnt work, then you need to figure out which packages are causing conflict and add this line into your package.json

#for npm users
overrides: {
packagename: "add local version here"
}


#for yarn users
resolutions: {
packagename: "add local version here"
}
