Yarn unmet peer dependency

• @2021-12-30
• This is so frequently asked, hence it's hard to find a good answer, so I note it down here.
• peer dependency is a week dependency, written in package.json, peerDependency and is not installed by yarn install (because the developer of the package decided so).
• Reason here from yarnpkg/yarn:

  Situation:

  • Your app directly depends on modules A and C
  • Module A directly depends on module B
  • Module C has peer dependency on module B Outcome:

  • Yarn throws warnings into the console about peer dependency B being unmet for module C, NPM does not.
