Your version of app-scripts is maybe 2 years old. Is this a legacy project?


Yes it is - This app contains woocommerce booking api’s that I want to be able to connect my woocommerce store to an app


There might be a lot of incompatibilities then. If you’re new, you’re probably better off building a few tutorials first. This sounds like a potential landmine. You might be a couple weeks away from being able to work on this project. Sorry.


I looked up the version and it was released 4 May 2017. So, ten months ago. Would rather plough ahead.


Well, you will have to downgrade your macOS then - because the one you are using just doesn’t seem to be supported by node-sass which is used by this very old app-scripts version.

Alternatively you might try to use to update the project, from Ionic 3.1.1 to a current version should not be too much work.


Thank you I will try that.


$> npm rebuild node-sass

$> npm uninstall node-sass && npm install node-sass
(again, with -g if necessary).

This problem occur when you change NodeJs version for example
