Just updated the Ionic CLI from 3.20.0 to 4.0.0. Now
ionic lab doesn’t work anymore. Here is the message I get:
[INFO] Looks like @ionic/lab isn't installed in this project. This package is required for Ionic Lab. For more details, please see the CHANGELOG: https://github.com/ionic-team/ionic-cli/blob/master/packages/ionic/CHANGELOG.md#4.0.0 [ERROR] A utility CLI has unexpectedly closed. The Ionic CLI will exit. Please check any output above for error details.
Is there anything to be installed?
