When ejected a No bundle URL present. error crashes the build.

[karloluis]

Description

After successfully running the default App with Expo I tried to eject it and have it working without it. Once ejected the Build succeeded but when running yarn run ios (Working from a Mac Book w/ Xcode) a error pupped up.

Expected Behavior

After running yarn run eject I expected the yarn run ios build and run the default app successfully.

Observed Behavior

The build succeeded but when running the packager/emulator errors with the .jsbundle where crashing.

Error text goes here!

Environment

Please run these commands in the project folder and fill in their results:

• npm ls react-native-scripts: n/a
• npm ls react-native: 0.47.2

Reproducible Demo

1. Eject generated CRNA w/ TS script.
2. Run ios script

PS noted that this might be a react-native related issue, but have not found a work around for either JS nor TS.

I still have the same issue with android. Everything works fine when I run the app via Expo. But when I eject it and then run it with yarn run android I get the following error :

You first need to start the bundler .

In one terminal type ... npm start (This command start the bundler )
In a second terminal type ... npx react-native run-ios

( Or equivalents to npm and npx react-native )
