回答1:

I had the same error and the problem was that I built the app in Release mode but the main.jsbundle was dev mode.

Using react-native@0.61.5

I stopped the Metro process and run again

react-native run-ios --configuration Release --device --scheme="MyTargetScheme"

回答2:

For us the issue was that we were (manually) building the RN bundle for our production app without setting the dev value in the react-native CLI.

When testing on simulator or device with a debug configuration in Xcode, this was not a problem. But since we archive for the App Store with a release config, we were seeing this crash in production.

The react-native bundle command has the --dev switch set to true by default. So the solution was simply to add --dev false to the bundle command.

In my case, my issue is resolved by node -v changes.

Initially I have used node 9.4.0 and then I have changed the node to 12.

Due to this version change the above error occurs.

So I have changed to node 9.4.0 and rebuild the app in release mode. It works fine

Any one know why the node version changes failed to bundle the app in release mode
