Hi, I’m considering migrating my app to Ionic 2 and TypeScript (from Ionic 1), so I’m just trying to get a basic tutorial / playground up and running with ionic start and ionic serve. However, when I do ionic serve, the browser is just giving a blank screen and the console shows that it has failed…

I had a similar issue and once I updated the CLI to the latest and it worked. You can try that

I have the same problem with --ts option and without this option The error Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:8100/build/js/app.bundle.js I don’t see any build folder in my project. No cordova plugins Mi ionic info Your system inform…

Well, I have upgraded to beta 19 (I was using beta 17) and the problem seems to have gone… although I’m not sure whether the problem was resolved by using b19 instead b17 or some side effect of whatever the hell npm install ionic@beta did under the covers. There is certainly something flaky in ther…

Sorry for the headache all, the starters come with the new package name, so if you have an old version of the CLI it will be looking for the wrong package and won’t know to run build. Upgrading to beta.19 npm install -g ionic@beta should fix things.

Check that you don’t have any TypeScript errors showing up in the CLI (these won’t show in the console, so everything might appear to be fine). In previous versions a TypeScript error wouldn’t stop your app from compiling and working, but now the app.bundle.js file won’t successfully compile if ther…
