Problem installing npm express on windows-CodePudding

this is my first time working with npm and I can't seem to install express. I have reviewed other questions on SO but the errors that I am getting seem to be a bit different.

$ npm install express
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

I am using a corporate laptop so this is perhaps where the issue lies. Any help would be greatly appreciated.

CodePudding user response：

I have seen this before on corporate laptops, specifically with npmjs.org. What sometimes companies do is block traffic entirely or re-encrypt the SSL connection through their datacenter (either forcing LAN traffic or requiring you to VPN to get internet and then doing it internal before leaving to the broad internet). This can wreak havoc on endpoints that they don't know anything about or decide they allow list instead of specifically blocklist. What your seeing there is your laptop being told there's no traffic allowed here (ECONNREFUSED).

Your best bet is to talk to IT dept, and see if they can let you through.

CodePudding user response：

I solved it. Quite a simple fix actually. I just tried to install the package when I was NOT connected to my companies servers :-/
