[bug\_fix] ERR\_PNPM\_PEER\_DEP\_ISSUES  Unmet peer dependencies

Either set 'strict-peer-dependencies=false' in .npmrc to downgrade to warning-only behavior \(like npm/yarn\), OR explicitly add the missing peer dependencies to your project's dependencies/devDependencies in package.json so pnpm can link them correctly.

Journey Context:
You migrate an existing React project from npm to pnpm for faster installs. Running 'pnpm install' immediately hard-fails with 'ERR\_PNPM\_PEER\_DEP\_ISSUES' listing react@^17.0.0 as unmet peer of various packages. npm used to just warn or auto-install. You check pnpm docs and learn it enforces strict peer dependency satisfaction by default. You consider setting strict-peer-dependencies=false, but instead decide to explicitly add react@17 to package.json devDependencies to properly satisfy the peer contract. Install succeeds with clean peer dependency tree because pnpm can now properly link the peer dependencies through its content-addressable store.
