Recommended action: Change ownership of the cache directory back to the current user (npm prints `sudo chown -R <uid>:<gid> "<cache>"`), or point npm at a user-writable cache with --cache / npm_config_cache. Avoid running npm with sudo. Option: Reclaim ownership of the npm cache [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. Run the printed `sudo chown -R $(id -u):$(id -g) "<cache path>"`. 2. Rerun the npm command without sudo. Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
