cordova plugin add org.apache.cordova.contacts --nofetch

The cordova 7 uses the npm to install the plugins, and probably your npm is
not globally installed, or misconfigured.

When i run beloaw command:-
cordova plugin add org.apache.cordova.contacts --nofetch

Error:-

Error: Registry returned 404 for GET on https://registry.npmjs.org/org.apache.co

check in your project

first remove contacts plugin from your project and again install that plugin
check is it working?

i think it will not work

because cordova team removed this plugin

see here:-

https://cordova.apache.org/news/2017/11/27/Deprecation-of-cordova-contacts-plugin.html

This means that the Cordova development community will not be doing any more work on this plugin.

You can continue to use this plugin as-is in existing and new applications

but any further issues will not be fixed by the Cordova team.

Yes

but now i am not able to install plugin

please suggest me
