The HTTP 500 Internal Server Error indicates a problem on the npm registry server side. This is usually temporary and outside your control, requiring you to wait and retry.
HTTP 500 is a generic server error indicating something went wrong on the npm registry's side. Unlike 4xx errors which indicate client problems, 5xx errors mean the server encountered an unexpected condition. This error is typically temporary - the registry team monitors and fixes these issues quickly. It could be due to registry maintenance, infrastructure problems, or unexpected load.
Verify if there's an outage:
# Visit status page
open https://status.npmjs.org
# Or check Twitter
# @npm_supportMost 500 errors are temporary:
# Wait a few minutes
sleep 300
# Retry the command
npm installUse a mirror if available:
# Temporarily use a mirror
npm install --registry https://registry.npmmirror.comSometimes cached bad responses persist:
npm cache clean --force
npm installFor production deployments, always have a fallback plan for registry outages. Consider using a local npm proxy (Verdaccio, Nexus) that caches packages. In CI/CD, implement retry logic with exponential backoff. Lock files (package-lock.json) help ensure reproducibility even if specific versions become temporarily unavailable.

npm ci --prefer-offlineIf error continues for a specific package:
1. Check github.com/npm/cli/issues
2. Report at npm.community
