It seems that every time I work on an Ionic 2 app and Want to go back and continue working on my ionic 1.7.14 app my Ionic CLI thinks I want to use Ionic 2 and I have to re-install ionic 1.7.14 in order to run simple ionic commands… I get this… ``` $ ionic info WARN: ionic.project has been renamed to ionic.config.json, please rename it. Uh oh! Looks like you're missing a module in your gulpfile: Cannot find module 'bower' Do you need to run `npm install`? ``` In the past I have switch to Node 4.4.4 and now I need to also re-install ionic 1.7.14 via npm to get my ionic 1 projects to build and run CLI commands… What can be the issue? ---
