Hi,
I've gone through your requirement to build ionic cordova app in your PC.
Do you want to build it for ios or android? Which version of Ionic and Cordova are you using?
IOS : install latest xcode and sdk and then try to build using ionic cordova build ios.
Android : install android sdk 25+, jdk, gradle then try to build using ionic cordova build Android.
Its my pleasure to complete this task for you in short period if you are still having issue in building app.
I've 3+ years of experience in Ionic and other Cross Platform Apps Development so I assure you to complete this.
