npm WARN Could not resolve dependency: peer xxx

Peer Dependency Warning

A package expects a peer dependency (e.g., React, webpack) that isn't installed or has a version mismatch.

Common Causes

Peer not installed
Version mismatch (e.g., React 17 vs 18)
Monorepo with conflicting versions
Legacy package with outdated peer range

Fixes

1. Install the peer explicitly
```
npm install react@^18.0.0
```
2. Use --legacy-peer-deps to bypass
```
npm install --legacy-peer-deps
```
3. Override in package.json
```
"overrides": { "react": "^18.0.0" }
```

Still not fixed?

• Search the exact error message on Stack Overflow or GitHub Issues
• Check the official docs for the language or tool
• Ensure your versions (Node, Python, npm, Docker) are up to date
• Try in a minimal reproduction (new project, single file)
