Report #7303

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

Add the missing peer dependencies explicitly to your devDependencies, or create a .npmrc file in the project root with strict-peer-dependencies=false to downgrade the error to a warning. Root cause: pnpm does not install peer dependencies automatically \(unlike npm 7\+\) and strict-peer-dependencies is true by default in pnpm 7\+, causing hard failures when peers are missing or conflict.

Journey Context:
You clone a repository that uses pnpm. You run pnpm install and it immediately fails with ERR\_PNPM\_PEER\_DEP\_ISSUES, listing 'react@>=16.8.0' as an unmet peer of 'react-dom'. You check package.json and see react is not listed. You realize that unlike npm, pnpm requires you to explicitly add peer dependencies to your own dependencies. You run pnpm add -D react@18, which adds it to devDependencies. Running pnpm install again succeeds. Alternatively, for a quick fix in a legacy project, you echo 'strict-peer-dependencies=false' >> .npmrc and reinstall.

environment: pnpm 6\+ \(especially 7\+ with strict defaults\), projects with React/Vue/Angular peer dependencies. · tags: pnpm err_pnpm_peer_dep_issues peer-dependencies strict-peer-dependencies · source: swarm · provenance: https://pnpm.io/npmrc\#strict-peer-dependencies
