I keep getting this error with various different Ionic script commands:
UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Cannot find module 'acorn'
I’ve tried updating to the latest version of ionic-app-scripts to no avail. I’m running an older version of Ionic because I’ve been unable to upgrade without a serious issue.
