removed 182 packages, and changed 3 packages in 28s

I updated manually TLS 1.2, rebooted my PC and newly installed Node-v16.11.0 and npm 8.0.0.

I'm still getting this error while installing npm install --save firebase.

Answer 1

Since the beginning of October, 2021 (announcement) the npm registry must use https, not plaintext http. To resolve the issue:

1. Check the registry of your npm: npm config get registry

2. If it shows any link starting with http only then you need to update the registry to use https secure TLS based version:

   npm config set registry https://registry.npmjs.org/
   

This will update registry and resolve your issue.
