old HTC android phone can not receive react-native build

Question

I have an HTC Desire 510 running Android 4.4.2.

Earlier in the year, I was able to deploy react-native apps to it, back when react-native init still generated index.android.js and index.ios.js in the project root folder.

Today, it seems react-native init only generates one index.js file in the project folder (as explained in this release not here). So now when I run the command react-native run-android to deploy my app to my phone, I get the error message:

Cannot find entry file index.android.js in any of the roots: ["C:\Users\John\Projects\ReactNative\htcandroidapp"]

How do I get a react-native app to deploy to my old HTC Desire 510 phone? I have no problem deploying the react-native app to my newer phones.
