Error: Please, upgrade your dependencies to the actual version of core-js@3
You should be able to simply update the version of the core-js module that is requested within the warning message:
npm install --save core-js@^3
For what it's worth npm has a nifty feature that lets you see which packages are outdated
npm outdated
You can also update packages to the latest versions using the update command
you can run 'npm audit fix', which will update the dependencies that are causing update and version errors
Below steps solved the issue for me,
npm i --package-lock-only
npm audit fix
--package-lock-only This will determine versions of packages to install using package.json, and then create a package-lock.json file with its resolved versions if none exists, or overwrite an existing one.
audit fix Scan your project for vulnerabilities and automatically install any compatible updates to vulnerable dependencies
