getting error gradlew.bat installDebug after installing react navigation and gesture handler

Question

I create the new react native app using command react-native init appName. After the app created successfully install it in my device using command react-native run-android, it installed successfully, and works fine... no issue

but as soon I install react navigation and gesture handler I am getting the error that Command failed: gradlew.bat installDebug after running command react-native run-android I don't know what's wrong... my old react native projects are working perfectly fine.

Yesterday I run the command gradlew clean in one of my old projects... is this affecting my new project?

This is the complete error:

  FAILURE: Build failed with an exception.

  Settings file 'D:\React Native Apps\Practice\newapp\android\settings.gradle' line: 3

Have you linked react-native-gesture-handler? – Bihari

yes I did link... – Cordie

Did you make the modification to MainActivity.java? – Bihari

Yes I did as mentioned in react navigation documentations... added some files – Cordie

posted the full error... it says some problem in settings.gradle file but its same as my old projects – Cordie

Answer 1

Oh yeah, it´s a bug i think with RN 0.58 link command

open settings.gradle with a text editor from => 'D:\React Native Apps\Practice\newapp\android\settings.gradle'

replace all '\' with '/' , in my case i had to replace '..\node_modules\react-native-gesture-handler\android' with '../node_modules/react-native-gesture-handler/android'

then react-native run-android

thanks a lot we are all so bored cause of these bugs from RN :( – Subcontinent

As a sidenote, this bug is not caused by react native, instead its caused by react native cli – Greenback

Make sure you already have installed python 2 and last version of jdk And make sure you have already set ANDROID_HOME And you should follow this structure : https://facebook.github.io/react-native/docs/getting-started.html
