Since the recent release of @atlaskit.icon 18.x my project is not building anymore due to the following: “Cannot find module: ‘…/src/components/Icon’. Make sure this package is installed.”.
I created a new project with Create React App an included the 18.x version to reproduce the error. With 17.x everything is working just fine.
Thanks for reporting it @carpedemus. This should be fixed in version
