Getting “java.lang.UnsatisfiedLinkError: couldn't find DSO to load: libhermes.so” error

Question

I\'m in the process of migrating a React Native project from react-native version 0.58.5 to 0.60.4.

For the Android part I\'ve done all the changes mentioned here

Answer 1

I solved this problem by this steps

1. install hermesvm : npm i hermesvm
2. install jsc-android : npm i jsc-android

3.add this lines to app/build.gradle

project.ext.react = [
   entryFile: "index.js" ,
   enableHermes: false
]

def jscFlavor = 'org.webkit:android-jsc:+'
def enableHermes = project.ext.react.get("enableHermes", false);


dependencies {
   if (enableHermes) {
       def hermesPath = "../../node_modules/hermesvm/android/";
       debugImplementation files(hermesPath + "hermes-debug.aar")
       releaseImplementation files(hermesPath + "hermes-release.aar")
    }
   else { implementation jscFlavor }

4. add this jsc-android block to your android/build.gradle:

     allprojects {
       repositories {
         maven {
           url("$rootDir/../node_modules/react-native/android")
         }
         maven {
            url "$rootDir/../node_modules/react-native/android"
         }
         google()
         jcenter()
       }
     }
