ionic update-notifier-cordova.json' You don't have access to this file
Deleting the file wont be a right option, the following approach worked out for me. The root cause of this issue is because of the Cordova-cli permissions.
Step 1: Uninstallcordova and install it again.
sudo npm remove -g cordova Step 2: Install with the following command
sudo npm install -g --unsafe-perm=true cordovaMake sure it installs the recent version, by typing $ ionic info you can see the Cordova CLI versions
Step 3: Secure the permissions for the following folders
sudo chown -R <username> /Users/<username>/.config/configstore/sudo chown -R <username> /Users/<username>/.cordova/ionic build ios - Should work like charm
