Install repairs
Fix broken npm installs and get back to building.
When `npm install` fails, you cannot run anything else. RinaWarp focuses on restoring a clean dependency tree so build and test commands work again.
Network blips, native module builds, and postinstall scripts all surface as install errors. The goal is a reproducible install path — usually `npm ci` on a correct lockfile.
Install failures block every other task
Symptoms we see often
- Install hangs or fails on postinstall scripts
- EACCES or permission errors writing to node_modules
- Integrity checksum failures or tarball errors
- Engine/node version mismatch warnings treated as errors
Common causes
- Lockfile out of date vs package.json
- Corrupted npm cache or partial node_modules
- Native addon build missing system toolchain
- Registry proxy or offline mirror misconfiguration
How RinaWarp fixes it
RinaWarp Terminal Pro follows the Observe → Plan → Approve → Execute → Proof workflow. Nothing executes without your approval.
- Diagnose whether the failure is network, permissions, native build, or resolution
- Clean install path: remove node_modules, use lockfile, retry
- Fix package.json scripts or versions if postinstall is broken
- Verify with build/test after install succeeds
Before and after
Representative terminal output — your project will differ, but the verification pattern should look like this.
After verification
Removed broken postinstall hook Regenerated lockfile from package.json npm ci — completed npm test — passed
