My netlify site name: with-love-irene

I would like to deploy this, however, I kept encountering ionic command not found even though I have already run npm i -D @ionic/cli locally in terminal before pushing the project again.

Hiya, sorry you are having trouble with your build.

This Support Guide contains a ton of useful debugging tips that can likely help you solve your problem :slight_smile: Additionally, this Support Guide houses all of our resources for debugging build and deploy issues.

We also recommend trying to search the forums with the build error you encountered - it’s likely your question was already asked by someone else!
