Unable to locate the index.js entry file in React Native

I have a simple React Native application. I am attempting to test it on a virtual Android device by navigating to the project and running npm start -- --reset-cache. After terminating the process, I enter the command react-native run-android. Despite having an active Android device, I encounter the following error:

The development server returned a response error with code 404 URL: http://10.0.0.2:8081/index.bundle?platform=android&dev=true&minify=false Body... "Cannot find the entry file index.js in any of the roots:[\"c:\\projects\\HelloRN]"....

Despite having an index.js file in the root of the project, I continue to see this error even though Metro Bundler is running on port 8081. The version of React Native being used is 0.51.0.

Answer №1

Here are a couple of options to consider:

  1. If the index.js file is not located in the project root directory
  2. In certain scenarios, React Native may have trouble reading index.js because it is looking for index.ios.js and index.android.js. To address this, you can try duplicating the index.js file and renaming it as index.android.js and index.ios.js respectively

Answer №2

The issue stemmed from permissions. Upon creating the same project on a different partition, excluding the C: drive where Windows is located, the project performed flawlessly and was able to detect the index.js file.
