Two projects in same time (Ionic 2 and Ionic 3)

Ionic Framework ionic-v3
1

I have two projects, one on Ionic 2.2.3 and another with the last version of Ionic 3. But unfortunately I’m having to uninstall and install a version of Ionic whenever I change the project, because of the incompatibility of the new CLI version.

Is there a more efficient way to switch the IONIC 2 and IONIC 3 versions (including your CLI) without having to uninstall and install them?

Hi there!

Soo there’s some confusion here. ionic 2.2.3 sounds like you’re talking about the CLI, not the framework, ionic-angular.

In this case, the Ionic-cli 3.x version is what you should be using for all your ionic projects. Regardless of what version of the framework you’re using (ionic-angular 2.x or ionic-angular 3.x), the 3.x version of the CLI will work.

To add on what mike already said:

Run ionic info with your Ionic v3 CLI in both project directories to get the real framework, ionic-angular, version (and also loads of other useful output).

When I try to run “ionic serve” I got this error:

Your app-scripts version is pretty old. I’d update it to the latest, currently 1.3.7.
