this error in commond promt, Couldn’t find ionic.config.json file. Are you in an Ionic project?
this happens when you run ionic commands from outside ionic project folder. make sure to navigate to ionic project folder and then run ionic commands.
In command prompt navigate to ionic project folder cd path-to-ionic-folder and then run your command.
What is the output of ionic info? We have to know which Ionic CLI version you are using.
this is happening when you are not in your project folder in cmd
If you have not this problem then you have to create a new project and copy all content in that
