Report #104329

[bug\_fix] npm ERR\! code EINTEGRITY - integrity checksum failed

Clear npm cache with \`npm cache clean --force\` and reinstall. If that fails, delete \`node\_modules\` and \`package-lock.json\`, then run \`npm install\` again.

Journey Context:
I was installing dependencies on a CI server and got EINTEGRITY errors for a package. The error said the integrity hash in the lockfile didn't match the downloaded tarball. I assumed network corruption or a malicious package. After clearing the cache with \`npm cache clean --force\` and retrying, the install succeeded. The root cause: npm caches tarballs and verifies their integrity against the lockfile; if the cache is stale or corrupted \(e.g., from a partial download or proxy issues\), the check fails. Clearing the cache forces npm to re-download fresh copies.
