Ionic serve not working in Ionic 3

Question

My Ionic info:

cli packages: (/usr/lib/node_modules)

@ionic/cli-utils  : 1.9.2
ionic (Ionic CLI) : 3.9.2

global packages:

Cordova CLI : 7.0.1 

local pack         


        

Answer 1

I have faced such a problem, tried a fresh new app, worked perfectly, tried another old app, also worked perfectly.

Tried to stop using some modules (clipboard in my case and another one), solved the problem, in my case it was an error in the way I am importing or using it.

ionic 5 is my ionic version

Hope this will help someone
