Had the same issue when I cloned a react-native repo to Linux and tried to run the app in the emulator. First is to have all your environment up and running. If that is the case, for me it was the permission issue for the gradlew file. Go to the android folder in your app and: chmod +x gradlew This answer was provided by Badmus Taofeeq in the post Clone and run react native projects from GitHub.You can also see on that page which commands to run to start the app. Hope you find something useful in this.
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.
I remember yesterday I run the command gradlew clean in one of my old project.. is this effecting on my new project?
I would be really thankful if someone helps
This is complete error

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
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
I am trying to link this library called react-native-text-detector.
However, I consistently get an error saying Command failed: gradlew.bat installDebug
I have tried changing the '\' in settings.gradle to '/'. However, the same error still pops up
All I have been doing is this
react-native init textDetectorTesting
npm install --save react-native-text-detector
react-native link
This is the error I received
