I faced the same issue with a new application created with react-native init. The problem is that the hermesCommand extra property is missing in the app-level build.gradle file. I solved the problem by adding the correct Hermes Command path, like so:

project.ext.react = [
    enableHermes: true,  // clean and rebuild if changing
    hermesCommand: '../../node_modules/react-native/sdks/hermesc/%OS-BIN%/hermesc'
]

NOTE: Setting the path to ../../node_modules/hermes-engine/%OS-BIN%/hermesc instead will cause a conflict between Hermes versions, which will throw the runtime error Compiling JS failed: Wrong bytecode version. Expected 85 but got 84, causing the app to crash as soon as it starts.

I hope this helps 🙂

@cervisebas were you able to build successfully on windows 10 i have been having error with my build on windows checkout the issue here #34084

I solved the problem by adding the correct Hermes Command path, like so:

Thanks for sharing this @JoseLion That sounds like a potential bug though.
The hermesCommand config has a sensible default which is the same value you're setting:

react-native/react.gradle

Lines 117 to 124 in 71e8921

	// 3. If the react-native contains a pre-built hermesc, use it.
	def prebuiltHermesPath = "node_modules/react-native/sdks/hermesc/%OS-BIN%/hermesc"
	.replaceAll("%OS-BIN%", getHermesOSBin())
	.replace('/' as char, File.separatorChar);
	def prebuiltHermes = new File(reactRoot, prebuiltHermesPath)
	if (prebuiltHermes.exists()) {
	return prebuiltHermes.getAbsolutePath()
	}

I wonder why you had to specify this value again.

[JoseLion]

@cortinico good point! I think I found the problem, and now it makes sense that it's only affecting Windows users.

The prebuiltHermes file is created with a path like C:\path\to\my\app\node_modules\react-native\sdks\hermesc\win64-bin\hermesc which then is checked with prebuiltHermes.exists(). The path to the HermesC folder is correct, but on Windows, the file hermesc will never exist because the file is actually hermesc.exe.

I think a simple solution could be to have a variable with the correct binary file depending on the OS:

def hermescBin = Os.isFamily(Os.FAMILY_WINDOWS) ? 'hermesc.exe' : 'hermesc'

I'll be happy to open a PR with this change if you agree it's a good approach 🙂

[wfern]

I can confirm the @JoseLion's fix, adding ".exe" in the file path works:

// 3. If the react-native contains a pre-built hermesc, use it.
def hermescBin = Os.isFamily(Os.FAMILY_WINDOWS) ? 'hermesc.exe' : 'hermesc'
def prebuiltHermesPath = ("node_modules/react-native/sdks/hermesc/%OS-BIN%/" + hermescBin)
        .replaceAll("%OS-BIN%", getHermesOSBin())
        .replace('/' as char, File.separatorChar);

Thanks @JoseLion!

I opened PR #34151 with this fix. I hope this helps 🎉

Added changes to my local react.gradle, and see the effect, but it still fails for me on a new project when I run gradlew clean.

[JoseLion]

@nibblesnbits I think the path for hermesc is incorrect when hermes-engine is built from source. Please take a look at this comment for more details 🙂

I can include a fix in the open PR, but I need some help to confirm if the proposed solution fixes the issue since I'm not currently using the new architecture 😅

[Suryanshshukla24]

add this in dependencies

def hermesPath = "../../node_modules/hermes-engine/android/"
debugImplementation files(hermesPath + "hermes-debug.aar")
releaseImplementation files(hermesPath + "hermes-release.aar")

inside if section

like this

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