Unable to update React and React Native with npm

I am trying to update to [email protected] and [email protected] but I am running into the following error:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: undefined@undefined
npm ERR! Found: [email protected]
npm ERR! node_modules/react
npm ERR!   react@"16.13.1" from the root project

npm ERR! 
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

I am currently on React 16.13.1 and React Native 0.63.4. Any idea on how to resolve this?

Just ran it with --verbose and got this as well:

You are probably running npm version 7. If so, try running your npm install commands with --legacy-peer-deps.

npm version 6 had a relatively lax approach to dependency conflicts, and npm version 7 is more strict, so will fail in situations where npm 6 did not. To go back to the npm 6 dependency resolution algorithm, use the --legacy-peer-deps flag. Another option would be to downgrade to npm 6.
