i find this solution in the Ionic Project, open: package.json Add this in it: “reflect-metadata”: “^0.1.3”, Then run this on console: npm install and Then run this: npm rebuild or npm rebuild node-sass Ready to run ionic serve to see your app 😉 ---

Found a fix for it: (but forgot to press post apparently) - Open your project folder - Open Package.json and add “reflect-metadata”: “^0.1.3”, ![image](https://global.discourse-cdn.com/ionicframework/original/3X/a/d/ad241bd1669e37bcd5e58161b26ccf72f69573df.png) - run npm install on the folder –\> ionic is no longer adding reflect-metadata to the package.json ---

Same error here today. Yesterday there were no issues with everything exactly the same (before the dependencies update from “ionic-angular”: “3.4.2” to “ionic-angular”: “3.5.0” in ionic2-app-base/package.json). ---

This solved my problem: `ionic start SomeProjectName blank --type=ionic-angular` Note “–type=ionic-angular” ionic serve now works. ---

There was another `@ionic/app-scripts` release that hopefully fixes that. Could you start a new project with `ionic start blank blank` and see if you can `ionic serve` that without problems? If you still get an error, please post your `ionic info` output of that project then.
