This error is happening since I update to ionic beta.5

[fperez-eypscap]

this happened to me, you need to update typescript to 2.9.2

[russcarver]

2.9.2 did the trick. I tried 3.0.1 first but that yielded the error ERROR in The Angular Compiler requires TypeScript >=2.7.2 and <2.10.0 but 3.0.1 was found instead.

[asleepinglion]

Yup, upgrading Typescript to 2.9.2 definitely resolves this problem. Would be great if someone could update the release notes to include the requirement to upgrade to Typescript 2.9.2. We had to fix a few issues within our app to do the upgrade as well since the errors didn't show while we've been locked in to 2.7.2 during our migration to v4.

Thank you for the issue! I've updated our changelog / release tag to include more information on the dependency changes:

Release: https://github.com/ionic-team/ionic/releases/tag/v4.0.0-beta.5
Changelog: https://github.com/ionic-team/ionic/blob/master/CHANGELOG.md#400-beta5-2018-08-27

Please let me know if there is a place I am missing that you refer to. Thank you!
