Hi @funkybaboon. This is rather a problem of the karma-jasmine dependency and since all the tasks run fine without the peer-dep, I'd rather not include it. If this is important to you, you could investigate over at the karma-jasmine repo why they require this peer-dep.

Additionally, this is the wrong package.json file. The template of package.json of the generated project is here: https://github.com/mwaylabs/generator-m-ionic/blob/master/generators/app/templates/package.json
