Ionic 2 device ready did not fire within 2000ms

问题:

I'm working within ionic 2 beta 11 on IOS platforms after run the app using ionic run ios a white screen appear and got the below message:

Native: deviceready did not fire within 2000ms. This can happen when plugins are in an inconsistent state. Try removing plugins from plugins/ and reinstalling them.

Any suggestion about that ? What's the problem exactly ?

This could be happening due to several issues, so you'd have to try a few things:

1. Reinstall the platform by running ionic state reset --platform
2. Reinstall your plugins by running ionic state reset --plugins before doing this please check that all your plugins are included in your package.json file.

3. Just like @joshmorony says here, try by changing the Content-Security-Policy from your index.html for this one:

   <meta http-equiv="Content-Security-Policy" content="default-src gap://ready file://* *; script-src 'self' 'unsafe-inline' 'unsafe-eval' *; style-src 'self' 'unsafe-inline' *”>

As mentioned in a comment of the other answer, in new version of the CLI you should delete the plugins and platforms folders manually. Then run :

ionic cordova prepare
