The ‘npx shadcn-ui@latest init’ cannot be executed on the company network. How can I init it offline?

Tried installing with the command, "npx shadcn-ui@latest init" in my company network. But it keeps throwing the following error.
I believe the company's network firewall is preventing access to this domain, so I hope to initialize it offline.
