Cannot install PactJS with the command npm i -S @pact-foundation/pact@latest

I am working in a proxy network within our corporation. I have not been getting any problems with installing npm library packages in general but now am faced with the error of not being install the latest Pact library.

When I run the command, npm i -S @pact-foundation/pact@latest, I get the following error:

Any insights would be appreciated
