[SOLVED] Cordova warning with ionic info

When I run ionic info I get the following warning:

 C:\ionic\test>ionic info

Your system information:

Cordova CLI: 6.1.0 (cordova-lib@undefined)
Ionic Version: 2.0.0-beta.3
Ionic CLI Version: 2.0.0-beta.22
Ionic App Lib Version: 2.0.0-beta.12
Node Version: v5.9.1

 Dependency warning - for the CLI to run correctly,
 it is highly suggested to install/upgrade the following:

 Please install your Cordova CLI to version  >=4.2.0 `npm install -g cordova`


OS is windows 10. The only diversion from a standard install is that I have created an .npmrc file as per the instructions here http://www.gajotres.net/ionic-2-installation-guide/. Is this warning material - ionic serve seems to work, but I have yet to try to build to a device ?
