Unable to run Alfresco-content-app

[Sadiya]

I have installed all the requirements nodejs, angular, npm, etc.

But when I am trying to run command 

npm install

I am getting error:

npm ERR! code E401
npm ERR! Unable to authenticate, need: NEGOTIATE, NTLM, BASIC realm="UHG"

npm ERR! A complete log of this run can be found in: /Users/saslam7/.npm/_logs/2023-09-26T07_18_08_061Z-debug-0.log

How can I run my app can you guide me ?? What problem it could be ??
