Report #100925

[bug\_fix] npm ERR\! code EINTEGRITY npm ERR\! sha512-abc... integrity checksum failed when trying to fetch a package from the npm registry.

Run \`npm cache clean --force\` to clear the local npm cache, then retry \`npm install\`. If that fails, also delete \`node\_modules\` and \`package-lock.json\` before retrying.

Journey Context:
A developer repeatedly saw EINTEGRITY errors when running npm install on a stable project. The issue persisted across network retries. They suspected a corrupted cache because the integrity hash didn't match. After clearing the npm cache with \`npm cache clean --force\` and retrying, the installation succeeded. The root cause is that npm checks package integrity against a stored hash from the registry; corrupted cache files or a registry inconsistency can cause mismatches.
