Ionic.native module for ionic v1 project

why does bower install native ionic 2.0 and npm 2.9 for an ionic v1 project?

when i use npm install ionic native --save it show "dependencies": { "ionic-native": "^2.9.0" }

and bower show "dependencies": { "ionic-native": "^2.0.3" }
i cant use a <script src=""> for ionic.native installed by npm, show me 404 on my index, but there is no problem if i use ionic.native from bower wich it located in www/lib/ionic-native/ionic.native,js , ani1 can show me a step by step tutorial for using the right way ionic.native on ionic v1 project??
