WELL NVM still expo error with no reason at all...

Expo SDK
1

I asked a question about this but i fixxed it … if I restart the server however I still get this error… First time I fixxed it it worked by switching the appentry. Then it worked as expected but I had to close the server to install a package and when I wanted to restart the server it just yields this again…

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: %s.%s%s, object,  You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check your code at withExpoRoot.js:26., 
    in ExpoRoot (at renderApplication.js:40)
    in RCTView (at AppContainer.js:101)
    in RCTView (at AppContainer.js:119)
    in AppContainer (at renderApplication.js:39)

Sounds like a React issue rendering a variable and not expo issue. What’s the code look like?

I think in this case my error was that my AppEntry file changes automatically if I install new packages… so it kept on swapping it to app.js even though my app was living somewhere else.

I fixxed it by importing my homefile into app.js and just default exporting it there so if expo decides to change the app entry file back to App.js it would still work!
