Error Log:

Error: Unable to resolve module ./index from D:\ReactNativeProject\testing\node_modules\react-native\scripts/.: The module ./index could not be found from D:\ReactNativeProject\testing\node_modules\react-native\scripts/..

What I have done to solve this?

1). I tried below command as I found a solution on Github

react-native start --reset-cache

2). I tried to remove the node-module folder and install it again but still not got success.

React Native Version: 0.59.2

Goto node_modules\react-native\scripts\launchPackager.bat

// comment this line

node "%~dp0..\cli.js" start

Add this line

node "%~dp0..\cli.js" start --projectRoot ../../../

After that run your project root cd android && gradlew clean and after run react-native run-android

run

react-native start -- --reset-cache

then run

react-native run-android

in separate command line window.

This works fine for me.

I also notice people fix it by writing some code in node_modules\react-native\scripts\launchPackager.bat, but writing code in node_modules isn't recommended.
