Serverless installation with npm fails: code E429

Serverless installation with NPM times out and returns the error below:

[root@ajirapsy2c cloud_user]# npm install -g serverless@1.49.0
npm ERR! code E429
npm ERR! 429 Too Many Requests - GET ://registry.npmjs.org/yaml-ast-parser

npm ERR! A complete log of this run can be found in:

[root@ajirapsy2c cloud_user]# 

I couldn’t upload all the screenshots for the /root/.npm/_logs/2020-02-17T12_48_28_131Z-debug.log, however this is the section where it starts to fail. I hope it helps you debug the issue:
