Unable to install serverless

for some reason ( not sure what happened) but I am unable to install the serverless framework. This is what I got

npm WARN deprecated superagent@3.8.3: Please note that v5.0.1+ of superagent removes User-Agent header by default, therefore you may need to add it yourself (e.g. GitHub blocks requests without a User-Agent header).  This notice will go away with v5.0.2+ once it is released.

I was able to do this before so I don’t know what I did wrong.

It sounds like some sort of permission error? I would post this over on the Serverless Framework issues page.
